Once known as Logan, now known as K1
NVIDIA has bet big on Tegra. Since the introduction of the SoC's first iteration, that much was clear. With the industry push to mobile computing and the decreased importance of the classic PC design, developing and gaining traction with a mobile processor was not only an expansion of the company’s portfolio but a critical shift in the mindset of a graphics giant.
The problem thus far is that while NVIDIA continues to enjoy success in the markets of workstation and consumer discrete graphics, the Tegra line of silicon-on-chip processors has faltered. Design wins have been tough to come by. Other companies with feet already firmly planted on this side of the hardware fence continue to innovate and seal deals with customers. Qualcomm is the dominant player for mobile processors with Samsung, MediaTek, and others all fighting for the same customers NVIDIA needs. While press conferences and releases have been all smiles and sunshine since day one, the truth is that Tegra hasn’t grown at the rate NVIDIA had hoped.
Solid products based on NVIDIA Tegra processors have been released. The first Google Nexus 7 used the Tegra 3 processor, and was considered the best Android tablet on the market by most, until it was succeeded by the 2013 iteration of the Nexus 7 this year. Tegra 4 slipped backwards, though – the NVIDIA SHIELD mobile gaming device was the answer for a company eager to show the market they built compelling and relevant hardware. It has only partially succeeded in that task.
With today’s announcement of the Tegra K1, previously known as Logan or Tegra 5, NVIDIA hopes to once again spark a fire under partners and developers, showing them that NVIDIA’s dominance in the graphics fields of the PC has clear benefits to the mobile segment as well. During a meeting with NVIDIA about Tegra K1, Dan Vivoli, Senior VP of marketing and a 16 year employee, equated the release of the K1 to the original GeForce GPU. That is a lofty ambition and puts of a lot pressure on the entire Tegra team, not to mention the K1 product itself, to live up to.
Tegra K1 Overview
What we previously knew as Logan or Tegra 5 (and actually it was called Tegra 5 until just a couple of days ago), is now being released as the Tegra K1. The ‘K’ designation indicated the graphics architecture that powers the SoC, in this case Kepler. Also, it’s the first one. So, K1.
The processor of the Tegra K1 look very familiar and include four ARM Cortex-A15 “r3” cores and 2MB of L2 cache with a fifth A15 core used for lower power situations. This 4+1 design is the same that was introduced with the Tegra 4 processor last year and allows NVIDIA to implement a style of “big.LITTLE” design that is unique. Some slight modifications to the cores are included with Tegra K1 that improve performance and efficiency, but not by much – the main CPU is very similar to the Tegra 4.
NVIDIA also unveiled late last night that another version of the Tegra K1 that replaces the quad A15 cores with two of the company's custom designs Denver CPU cores. Project Denver, announced in early 2011, is NVIDIA's attempt at building its own core design based on the ARMv8 64-bit ISA. This puts this iteration of Tegra K1 on the same level as Apple's A7 and Qualcomm's Krait processors. When these are finally available in the wild it will be incredibly intriguing to see how well NVIDIA's architects did in the first true CPU design from the GPU giant.

Introduction and Unboxing
We've been covering NVIDIA's new G-Sync tech for quite some time now, and displays so equipped are finally shipping. With all of the excitement going on, I became increasingly interested in the technology, especially since I'm one of those guys who is extremely sensitive to input lag and the inevitable image tearing that results from vsync-off gaming. Increased discussion on our weekly podcast, coupled with the inherent difficulty of demonstrating the effects without seeing G-Sync in action in-person, led me to pick up my own ASUS VG248QE panel for the purpose of this evaluation and review. We've generated plenty of other content revolving around the G-Sync tech itself, so lets get straight into what we're after today - evaluating the out of box installation process of the G-Sync installation kit.
All items are well packed and protected.
Included are installation instructions, a hard plastic spudger for opening the panel, a couple of stickers, and all necessary hardware bits to make the conversion.

Small form factor cases and the push to Mini ITX designs took a dramatic journey during 2013 as the popularity of the smaller PC once again became a popular trend. Though a company like Shuttle, that hardly exists in the form it did in 2004, was the first PC hardware company to really drive home the idea of an SFF system design, many other players have released compelling products helping to strengthen it as one of the unique possibilities for enthusiast PCs.
Even better, though a Mini-ITX based platform could mean limited options for hardware and performance, with companies like ASUS, EVGA, BitFenix and others in the mix, building an incredibly fast and powerful gaming machine using small hardware is not only easy but can be done at a lower price than you might expect.
One entry that found its way to our offices this December comes from Silverstone in the form of the Raven Z, RVZ01 case. This case includes unique features and capabilities including the ability to support nearly any high end graphics card on the market (dual slot or single), space for larger heatsinks and even liquid coolers along with a home theater friendly look and style. Oh, and it's
the same almost the same design that Valve used for its beta Steam Machines as well. (Update: Turns out the size of the Steam Machine is actually a fair bit smaller than the Silverstone RVZ01.)
Sapphire Triple Fan Hawaii
It was mid-December when the very first custom cooled AMD Radeon R9 290X card hit our offices in the form of the ASUS R9 290X DirectCU II. It was cooler, quieter, and faster than the reference model; this is a combination that is hard to pass up (if you could buy it yet). More and more of these custom models, both in the R9 290 and R9 290X flavor, are filtering their way into PC Perspective. Next on the chopping block is the Sapphire Tri-X model of the R9 290X.
Sapphire's triple fan cooler already made quite an impression on me when we tested a version of it on the R9 280X retail round up from October. It kept the GPU cool but it was also the loudest of the retail cards tested at the time. For the R9 290X model, Sapphire has made some tweaks to the fan speeds and the design of the cooler which makes it a better overall solution as you will soon see.
The key tenets for any AMD R9 290/290X custom cooled card is to beat AMD's reference cooler in performance, noise, and variable clock rates. Does Sapphire meet these goals?
The Sapphire R9 290X Tri-X 4GB
While the ASUS DirectCU II card was taller and more menacing than the reference design, the Sapphire Tri-X cooler is longer and appears to be more sleek than the competition thus far. The bright yellow and black color scheme is both attractive and unique though it does lack the LED light that the 280X showcased.
Sapphire has overclocked this model slightly, to 1040 MHz on the GPU clock, which puts it in good company.
|AMD Radeon R9 290X||ASUS R9 290X DirectCU II||Sapphire R9 290X Tri-X|
|Rated Clock||1000 MHz||1050 MHz||1040 MHz|
|Memory Clock||5000 MHz||5400 MHz||5200 MHz|
|TDP||~300 watts||~300 watts||~300 watts|
|Peak Compute||5.6 TFLOPS||5.6+ TFLOPS||5.6T TFLOPS|
There are three fans on the Tri-X design, as the name would imply, but each are the same size unlike the smaller central fan design of the R9 280X.

A relative new comer in the enthusiast space, Phanteks has taken the hearts and minds with their high-performance and innovatively designed thermal cooling solutions. The PH-TC12DX cooler features a massive dual-radiator tower actively cooled by two 120mm fans with a copper, nickel-plated CPU base plate. The cooler cines packaged with support for all current Intel and AMD CPU socket offerings. To properly gage the PH-TC12DX's performance, we put it up against several similarly-classed air and water-based cooling solutions. At a retail price of $54.99, the Phanteks PH-TC12DX offers you solid performance without busting your bank.

The Phanteks PH-TC12DX cooler consists of a single tower radiator with four U-shaped heat pipes intersecting the its cooling fins. The cooler uses nickel-plated copper heat pipes to transfer the heat from the copper CPU base plate to the fins of the aluminum radiator for optimal heat transmission and dispersal. The tower is sandwiched by two high air flow 120mm fans for heat dispersion from the radiator. Phanteks went to great lengths to make sure the PH-TC12DX kept a sleek looking appearance from the black coloration of the radiator to the branded top-plate to hide the heat pipe termination points.

Phanteks includes everything you need to get the cooler up and running in your system: mounting kits supporting both Intel and AMD-based systems, dual PH-F120HP 120mm fans, fan mounting kits, a sleeved dual-ended fan power cable, and Phanteks PH-NDC thermal paste.
Introduction and Features
We have been reviewing Seasonic power supplies for over ten years here at PCPerspective and they have never failed to impress us. Seasonic is also one of the few companies that actually builds their own power supplies (along with supplying units to numerous other big-name brands). Seasonic has built a stellar reputation for producing some of the best PC power supplies on the market today. In their ongoing pursuit to continuously improve their products, Seasonic has recently introduced the S12G Series, which includes four models: S12G-450, S12G-550, S12G-650, and the S12G-750 that we will be taking a detailed look at in this review. Here are a few of the highlights offered by the new S12G Series power supplies.
• 80Plus Gold certification
• Standard all in one, flat black cabling
• High +12V Output
• Smart and Silent Fan Control (S2FC)
• S12G-750/650: PCI-E 8P/6P x 4, SATA x 10, 4P Molex x 4, FDD x 1
• S12G-550/450: PCI-E 8P/6P x 2, SATA x 8, 4P Molex x 3, FDD x 1
• Worldwide 5-Year Warranty
The S12G Series is targeted towards gamers and PC enthusiasts who want solid performance at a user friendly price. To accomplish this Seasonic has designed the S12G Series on the same basic platform as many of their premium products but has forgone a few features like modular cables and fanless operation for price conscious consumers. Retail prices are currently ranging from $79.99 USD for the S12G-450 to $109.99 USD for the S12G-750 (newegg.com, November 2013).
Here is what Seasonic has to say about the new S12G Series: “The S12G Series is the newest addition to Seasonic’s families of award winning retail products, representing the latest innovation of our engineering team. To meet the demands of users who are looking for reliable 80Plus Gold performance for gaming and overall usage, the S12G Series is designed to support Intel’s Haswell processors, features more SATA cables and is an affordable solution for a wide range of applications.”

EVGA Enters the Chassis Market
Cases are a funny thing. Some people spend more time fretting over the chassis of their new system than any other component while some builders simply could not care less about what "box" is holding the carefully selected components that power their gaming rig. While I can see both points of view, I think it is a shame to completely ignore the "look" of your system as it will be the one part of your design choices that you'll see on a daily basis.
EVGA has a great reputation in the enthusiast market thanks to its top of the line graphics cards and the emphasis of the company on enthusiast level products, water cooling and more. In recent years EVGA has branched into motherboards (again), power supplies and now cases. But rather than target a market that was saturated and dominated by a few big players, they decided to target the Mini ITX form factor. Having just recently released the Z87 Stinger Mini ITX motherboard, EVGA has created an ecosystem that allows a builder to use exclusively EVGA components with the new Hadron Air case.
In our video review below you'll see our overview of the design, the positive and negatives of the design and of small cases in general and my final thoughts on this rather impressive mITX design. After you are done watching it head down to the collection of photos below for a written analysis of the Hadron Air.
If you have never worked in a small form factor PC before, let me warn you up front - this is not as simple of a process as building a computer in a standard ATX case. Space is tight and doing simple things like routing cables from the motherboard to the hard drive can be a 10 minute ordeal. Additionally, sometimes the ORDER of installation can make a HUGE difference in the ease of the entire process so pay attention to other users that might have used your particular chassis.
Don't let its small size fool you though, the EVGA Hadron Air can pack a lot of punch. Using the latest mITX motherboard and graphics cards from EVGA's lineup you can literally build one of the most powerful gaming systems around in its small 6x12x12-in space!
What is the Hardware Leaderboard
What is a Leaderboard? If you have to ask you really haven't clicked on enough of the tabs at the top of PC Perspective! The Leaderboard consists of four different systems, each with a price target and are updated monthly. They start with the ~$500 budget system which is for general family or dorm usage but not for heavy gaming usage, though it can certainly handle many online games without issue. The Mid Range machine can be yours for around $1000 and packs enough power under the hood to handle productivity software and can give a console a run for its money when gaming. Things start getting more serious when you look at the High End machine, even while keeping the price around $1500 you start to see serious performance that will show you why PC Gaming is still far more popular than some would have you believe. Finally is the Dream Machine which doesn't have a specific price cap but is limited by a certain amount of common sense; you can slap four GPUs in the system but you really will not be getting a great return on your investment as the performance scaling does not continue to increase at a linear pace.
You may notice several components missing from the HWLB and there is a reason for that. Enclosures are a very personal choice for system builders and no ones desires are exactly the same. Dremel owners with a good imagination want a case that is easily moddable while pet owners want washable filters on their systems. Some may want a giant white case while others an unobtrusive and quiet enclosure and who can tell where you prefer your front panel connectors to be but you? Cooling solutions are again a personal choice, do you plan on getting the biggest chunk of metal you can find with three 140mm fans strapped to it or were you thinking of using watercooling, either a self contained CPU cooler or a custom built cooling loop that incorporates multiple components? The same applies to monitors with some gamers preferring to sacrifice colour quality and viewing angle for the refresh rates of a TN display while others have a need to pick up a professional quality display at over $1000 for when they are working. Size is always personal; just how big can you fit in your place? (Editor's note: we did include a couple of case recommendations in the build guide summary tables, in case you are interested though.)
So continue on to see the components that make up the current four builds of the Hardware Leaderboard. Once you have all your components you can reference Ryan's videos covering the installation of the parts into the case of your choice as well as installing your OS and Steam so you can get right to gaming and surfing.
The First Custom R9 290X
It has been a crazy launch for the AMD Radeon R9 series of graphics cards. When we first reviewed both the R9 290X and the R9 290, we came away very impressed with the GPU and the performance it provided. Our reviews of both products resulted in awards of the Gold class. The 290X was a new class of single GPU performance while the R9 290 nearly matched performance at a crazy $399 price tag.
But there were issues. Big, glaring issues. Clock speeds had a huge amount of variance depending on the game and we saw a GPU that was rated as "up to 1000 MHz" running at 899 MHz in Skyrim and 821 MHz in Bioshock Infinite. Those are not insignificant deltas in clock rate that nearly perfectly match deltas in performance. These speeds also changed based on the "hot" or "cold" status of the graphics card - had it warmed up and been active for 10 minutes prior to testing? If so, the performance was measurably lower than with a "cold" GPU that was just started.
That issue was not necessarily a deal killer; rather, it just made us rethink how we test GPUs. The fact that many people were seeing lower performance on retail purchased cards than with the reference cards sent to press for reviews was a much bigger deal. In our testing in November the retail card we purchased, that was using the exact same cooler as the reference model, was running 6.5% slower than we expected.
The obvious hope was the retail cards with custom PCBs and coolers would be released from AMD partners and somehow fix this whole dilemma. Today we see if that was correct.
A slightly smaller MARS
The NVIDIA GeForce GTX 760 was released in June of 2013. Based on the same GK104 GPU as the GTX 680, GTX 670 and GTX 770, the GTX 760 disabled a couple more of the clusters of processor cores to offer up impressive performance levels for a lower cost than we had seen previously. My review of the GTX 760 was very positive as NVIDIA had priced it aggressively against the competing products from AMD.
As for ASUS, they have a storied history with the MARS brand. Typically an over-built custom PCB with two of the highest end NVIDIA GPUs stapled together, the ASUS MARS cards have been limited edition products with a lot of cache around them. The first MARS card was a dual GTX 285 product that was the first card to offer 4GB of memory (though 2GB per GPU of course). The MARS II took a pair of GTX 580 GPUs and pasted them on a HUGE card and sold just 1000 of them worldwide. It was heavy, expensive and fast; blazing fast. But at a price of $1200+ it wasn't on the radar of most PC gamers.
Interestingly, the MARS iteration for the GTX 680 never occurred and why that is the case is still a matter of debate. Some point the finger at poor sales and ASUS while others think that NVIDIA restricted ASUS' engineers from being as creative as they needed to be.
Today's release of the ASUS ROG MARS 760 is a bit different - this is still a high end graphics card but it doesn't utilize the fastest single-GPU option on the market. Instead ASUS has gone with a more reasonable design that combines a pair of GTX 760 GK104 GPUs on a single PCB with a PCI Express bridge chip between them. The MARS 760 is significantly smaller and less power hungry than previous MARS cards but it is still able to pack a punch in the performance department as you'll soon see.

A not-so-simple set of instructions
Valve released to the world the first beta of SteamOS, a Linux-based operating system built specifically for PC gaming, on Friday evening. We have spent quite a lot of time discussing and debating the merits of SteamOS, but this weekend we wanted to do an installation of the new OS on a system and see how it all worked.
Our full video tutorial of installing and configuring SteamOS
First up was selecting the hardware for the build. As is usually the case, we had a nearly-complete system sitting around that needed some tweaks. Here is a quick list of the hardware we used, with a discussion about WHY just below.
|Processor||Intel Core i5-4670K - $222|
|Motherboard||EVGA Z87 Stinger Mini ITX Motherboard - $257|
|Memory||Corsair Vengeance LP 8GB 1866 MHz (2 x 4GB) - $109|
|Graphics Card||NVIDIA GeForce GTX TITAN 6GB - $999
EVGA GeForce GTX 770 2GB SuperClocked - $349
|Storage||Samsung 840 EVO Series 250GB SSD - $168|
|Case||EVGA Hadron Mini ITX Case - $189|
|Power Supply||Included with Case|
|Optical Drive||Slot loading DVD Burnder - $36|
|Peak Compute||4,494 GFLOPS (TITAN), 3,213 GFLOPS (GTX 770)|
|Total Price||$1947 (GTX TITAN) $1297 (GTX 770)|
We definitely weren't targeting a low cost build with this system, but I think we did create a very powerful system to test SteamOS on. First up was the case, the new EVGA Hadron Mini ITX chassis. It's small, which is great for integration into your living room, yet can still hold a full power, full-size graphics card.
The motherboard we used was the EVGA Z87 Stinger Mini ITX - an offering that Morry just recently reviewed and recommended. Supporting the latest Intel Haswell processors, the Stinger includes great overclocking options and a great feature set that won't leave enthusiasts longing for a larger motherboard.

Quality time with G-Sync
Readers of PC Perspective will already know quite alot about NVIDIA's G-Sync technology. When it was first unveiled in October we were at the event and were able to listen to NVIDIA executives, product designers and engineers discuss and elaborate on what it is, how it works and why it benefits gamers. This revolutionary new take on how displays and graphics cards talk to each other enables a new class of variable refresh rate monitors that will offer up the smoothness advantages of having V-Sync off, while offering the tear-free images normally reserved for gamers enabling V-Sync.
NVIDIA's Prototype G-Sync Monitor
We were lucky enough to be at NVIDIA's Montreal tech day while John Carmack, Tim Sweeney and Johan Andersson were on stage discussing NVIDIA G-Sync among other topics. All three developers were incredibly excited about G-Sync and what it meant for gaming going forward.
Also on that day, I published a somewhat detailed editorial that dug into the background of V-sync technology, why the 60 Hz refresh rate existed and why the system in place today is flawed. This basically led up to an explanation of how G-Sync works, including integration via extending Vblank signals and detailed how NVIDIA was enabling the graphics card to retake control over the entire display pipeline.
In reality, if you want the best explanation of G-Sync, how it works and why it is a stand-out technology for PC gaming, you should take the time to watch and listen to our interview with NVIDIA's Tom Petersen, one of the primary inventors of G-Sync. In this video we go through quite a bit of technical explanation of how displays work today, and how the G-Sync technology changes gaming for the better. It is a 1+ hour long video, but I selfishly believe that it is the most concise and well put together collection of information about G-Sync for our readers.
The story today is more about extensive hands-on testing with the G-Sync prototype monitors. The displays that we received this week were modified versions of the 144Hz ASUS VG248QE gaming panels, the same ones that will in theory be upgradeable by end users as well sometime in the future. These monitors are TN panels, 1920x1080 and though they have incredibly high refresh rates, aren't usually regarded as the highest image quality displays on the market. However, the story about what you get with G-Sync is really more about stutter (or lack thereof), tearing (or lack thereof), and a better overall gaming experience for the user.
Introduction and Design
Contortionist PCs are a big deal these days as convertible models take the stage to help bridge the gap between notebook and tablet. But not everyone wants to drop a grand on a convertible, and not everyone wants a 12-inch notebook, either. Meanwhile, these same people may not wish to blow their cash on an underpowered (and far less capable) Chromebook or tablet. It’s for these folks that Lenovo has introduced the IdeaPad Flex 14 Ultrabook, which occupies a valuable middle ground between the extremes.
The Flex 14 looks an awful lot like a Yoga at first glance, with the same sort of acrobatic design and a thoroughly IdeaPad styling (Lenovo calls it a “dual-mode notebook”). The specs are also similar to that of the x86 Yoga, though with the larger size (and later launch), the Flex also manages to assemble a slightly more powerful configuration:
The biggest internal differences here are the i5-4200U CPU, which is a 1.6 GHz Haswell model with a TDP of 15 W and the ability to Turbo Boost (versus the Yoga 11S’ i5-3339Y, which is Ivy Bridge with a marginally lower TDP of 13 W and no Turbo Boost), the integrated graphics improvements that follow with the newer CPU, and a few more ports made possible by the larger chassis. Well, and the regression to a TN panel from the Yoga 11S’ much-appreciated IPS display, which is a bummer. Externally, your wallet will also appreciate a $250 drop in price: our model, as configured here, retails for just $749 (versus the $999 Yoga 11S we reviewed a few months back).
You can actually score a Flex 14 for as low as $429 (as of this writing), by the way, but if you’re after any sort of respectable configuration, that price quickly climbs above the $500 mark. Ours is the least expensive option currently available with both a solid-state drive and an i5 CPU.
Streaming games straight from NVIDIA
Over the weekend NVIDIA released a December update for the SHIELD Android mobile gaming device that included a very interesting, and somewhat understated, new feature: Beta support for NVIDIA GRID.
You have likely heard of GRID before, NVIDIA has been pushing it as part of the companies vision going forward to GPU computing in every facet and market. GRID was aimed at creating GPU-based server farms to enable mobile, streaming gaming to users across the country and across the world. While initially NVIDIA only talked about working with partners to launch streaming services based on GRID, they have obviously changed their tune slightly with this limited release.
If you own a SHIELD, and install the most recent platform update, you'll find a new icon in your NVIDIA SHIELD menu called GRID Beta. The first time you start this new application, it will attempt to measure your bandwidth and latency to offer up an opinion on how good your experience should be. NVIDIA is asking for at least 10 Mbps of sustained bandwidth, and wants round trip latency under 60 ms from your location to their servers.
Currently, servers are ONLY located in Northern California so the further out you are, the more likely you will be to run into problems. However, oing some testing in Kentucky and Ohio resulted in a very playable gaming scenarios, though we did run into some connection problems that might be load-based or latency-based.
After the network setup portion users are shown 8 different games that they can try. Darksiders, Darksiders II, Street Fighter X Tekken, Street Fighter IV, Alan Wake, The Witcher 2, Red Faction: Armageddon and Trine 2. You are free to play them free of charge during this beta though I think you can be sure they will be removed and erased at some point; just a reminder. Saves work well and we were able to save and resume games of Darksiders 2 on GRID easily and quickly.
Starting up the game was fast, about on par with starting up a game on a local PC, though obviously the server is loading it in the background. Once the game is up and running, you are met with some button mapping information provided by NVIDIA for that particular game (great addition) and then you jump into the menus as if you were running it locally.
Introduction and Technical Specifications
Courtesy of Noctua
Noctua is a well known name in the enthusiast world for its high-end CPU cooler products. Their flagship cooler, the NH-D14, features a nickel-plated copper base with dual radiator towers actively cooled by low noise 120mm and 140mm fans. The NH-D14 can be used with all current Intel and AMD CPU offerings. The cooler was put to the test against other similarly classed air and water-based cooling systems to see just how well Noctua's design would hold up. The Noctua NH-D14 does not come cheap with a retail price at $99.99, but its performance and utility should make up for that initial outlay.

The Noctua NH-D14 cooler is everything you would expect in a premium CPU cooler - nickel-plating for corrosion resistance, twin-tower radiators for massive heat dissipation potential, and copper / aluminum hybrid design for optimal heat transfer from the CPU. Noctua designed the NH-D14 with a total of six heat pipes, laid out in a U-shaped design which passes through the copper base plate and terminates in the radiator towers. The bottom of the copper base plate leaves the factory ground flat and polished to a mirror-like finish, ensuring optimal interfacing with the CPU surface.

Noctua included the following components in with the base cooler: SecureFirm2™ multi-socket mounting kit, NF-P14 140mm fan, NF-P12 120mm fan, four fan mounting brackets, a dual-ended fan power cable, two single-fan low power cables, a case badge, and NT-H1 thermal compound.
PC Component Selections
It's that time of year again! When those of us lucky enough with the ability, get and share the best in technology with our friends and family. You are already the family IT manager so why not help spread the holiday cheer by picking up some items for them, and hey...maybe for you. :)
This year we are going to break up the guide into categories. We'll have a page dedicated to PC components, one for mobile devices like notebooks and tablets and one for PC accessories. Then, after those specific categories, we'll have an open ended collection of pages where each PC Perspective team member can throw in some wildcards.

Intel Core i7-4770K Haswell Processor
The Intel Core i7-4770K is likely the best deal in computing performance today, after to power just about any configuration of PC you can think of without breaking much a sweat. You want to game? This part has you covered? You want to encode some video? The four cores and included HyperThreading support provide just about as much power as you could need. Yes there are faster processors in the form of the the Ivy Bridge-E and even 10+ core Xeon processors, but those are significantly more expensive. For a modest price of $299 you can get what is generally considered the "best" processor on the market.
Corsair Carbide Series Air 540 Case
Cases are generally considered a PC component that is more about the preference of the buyer but there are still fundamentals that make cases good, solid cases. The new Corsair Carbide Air 540 is unique in a lot of ways. The square-ish shape allows for a division of your power supply, hard drives and SSDs from the other motherboard-attached components. Even though the case is a bit shorter than others on the market, there is plenty of working room inside thanks to the Corsair dual-chamber setup and it even includes a pair of high-performance Corsair AF140L fans for intake and exhaust. The side panel window is HUGE allowing you to show off your goods and nice touches like the rubber grommeted cable routing cut outs and dust filters make this one of the best mid-range cases available.
Another retail card reveals the results
Since the release of the new AMD Radeon R9 290X and R9 290 graphics cards, we have been very curious about the latest implementation of AMD's PowerTune technology and its scaling of clock frequency as a result of the thermal levels of each graphics card. In the first article covering this topic, I addressed the questions from AMD's point of view - is this really a "configurable" GPU as AMD claims or are there issues that need to be addressed by the company?
The biggest problems I found were in the highly variable clock speeds from game to game and from a "cold" GPU to a "hot" GPU. This affects the way many people in the industry test and benchmark graphics cards as running a game for just a couple of minutes could result in average and reported frame rates that are much higher than what you see 10-20 minutes into gameplay. This was rarely something that had to be dealt with before (especially on AMD graphics cards) so to many it caught them off-guard.
Because of the new PowerTune technology, as I have discussed several times before, clock speeds are starting off quite high on the R9 290X (at or near the 1000 MHz quoted speed) and then slowly drifting down over time.
Another wrinkle occurred when Tom's Hardware reported that retail graphics cards they had seen were showing markedly lower performance than the reference samples sent to reviewers. As a result, AMD quickly released a new driver that attempted to address the problem by normalizing to fan speeds (RPM) rather than fan voltage (percentage). The result was consistent fan speeds on different cards and thus much closer performance.
However, with all that being said, I was still testing retail AMD Radeon R9 290X and R9 290 cards that were PURCHASED rather than sampled, to keep tabs on the situation.
