NVIDIA has released version 2.0.1 of GeForce Experience. This update does not bring many new features, hence why it is a third-level increment to the version number, but is probably worthwhile to download regardless. Its headlining feature is security enhancements with OpenSSL under remote GameStream on SHIELD. The update also claims to improve streaming quality and reduce audio latency.
While they do not seem to elaborate, I assume this is meant to fix Heartbleed, which is an exploit that allows an attacker to receive a small snapshot of active memory. If that is that case, it is unclear whether the SHIELD, the host PC during a game session, or both endpoints are affected.
The new GeForce Experience is available at the NVIDIA website. If it is running, it will also ask you to update it, of course.

NVIDIA unveiled the GeForce GTX TITAN Z at the GPU Technology Conference last month, and the cards will be for sale soon from various partners. ASUS will be one of the first AIB partners to offer a reference TITAN-Z.
The ASUS GTX TITAN Z pairs two full GK110-based GPUs with 12GB of GDDR5 memory. The graphics card houses a total of 5,760 CUDA cores, 480 texture manipulation units (TMUs), and 96 ROPs. Each GK110 GPU interfaces with 6GB of GDDR5 memory via a 384-bit bus. ASUS is using reference clockspeeds with this card, which means 705 MHz base and up to 876 MHz GPU Boost for the GPUs and 7.0 GHz for the memory.
For comparison, the dual-GPU TITAN Z is effectively two GTX TITAN Black cards on a single PCB. However, the TITAN Black runs at 889 MHz base and up to 980 MHz GPU Boost. A hybrid water cooling solution may have allowed NVIDIA to maintain the clockspeed advantage, but doing so would compromise the only advantage the TITAN Z has over using two (much cheaper) TITAN Blacks in a workstation or server: card density. A small hit in clockspeed will be a manageable sacrifice for the target market, I believe.
The ASUS GTX TITAN Z has a 375W TDP and is powered by two 8-pin PCI-E power connectors. The new flagship dual GPU NVIDIA card has an MSRP of $3,000 and should be available in early May.

Sometimes I feel like this job just keeps getting stranger and stranger. Today is no expection.
After reciving just a tracking number, and no additional information from NVIDIA earlier this week, the mystery package finally arrived today. Upon initial inspection we had no idea what to expect.
When we opened the box, we were greeted by a polystyrene cooler with the logo of Bake Me a Wish, which only served to confuse us more.
As we opened the cooler, and the subsequent box inside of it, things started to make more sense.
Inside the box, we were greeted by a chocolate cake, accompanied by a card from NVIDIA.
As you may remember at this year's GTC Conference, NVIDIA announced that they had ported Valve's Portal to Android and would be releasing it for SHIELD. Today we were greeted with a reminder of that, and the message that we should be able to try it for ourselves.
A teaser from this year's GTC Keynote
While we can't talk about our experiences with Portal just yet, stay tuned to PC Perspective for more coverage of the NVIDIA SHIELD and Portal very soon!

GPU drivers have been a hot and sensitive topic at the site, especially recently, probably spurred on by the announcements of Mantle and DirectX 12. These two announcements admit and illuminate (like a Christmas tree) the limitations of APIs on gaming performance. Both AMD and NVIDIA have their recent successes and failures on their respective fronts. This will not deal with that, though. This is a straight round-up of new GPUs running the latest drivers... in Linux.
In all, NVIDIA tends to have better performance with its 700-series parts than equivalently-priced R7 or R9 products from AMD, especially in low-performance Source Engine titles such as Team Fortress 2. Sure, even the R7 260X was almost at 120 FPS, but the R9 290 was neck-and-neck with the GeForce GTX 760. The GeForce GTX 770, about $50 cheaper than the R9 290, had a healthy 10% lead over it.
In Unigine Heaven, however, the AMD R9 290 passed the NVIDIA GTX 770 by a small margin, coming right in line with it's aforementioned $50-bigger price tag. In that situation, where performance became non-trivial, AMD caught up (but did not beat). Also, third-party driver support is more embraced by AMD than NVIDIA. On the other hand, NVIDIA's proprietary drivers are demonstrably better, even if you would argue that the specific cases are trivial because of overkill.
And then there's Unvanquished, where AMD's R9 290 did not achieve triple-digit FPS scores despite the $250 GTX 760 getting 110 FPS.
Update: As pointed out in the comments, some games perform significantly better on the $130 R7 260X than the $175 GTX 750 Ti (HL2: Lost Coast, TF2, OpenArena, Unigine Sanctuary). Some other games are the opposite, with the 750 Ti holding a sizable lead over the R7 260X (Unigine Heaven and Unvanquished). Again, Linux performance is a grab bag between vendors.
There's a lot of things to consider, especially if you are getting into Linux gaming. I expect that it will be a hot topic, soon, as it picks up... ... Steam.

VR-Zone is claiming that this is the successor to NVIDIA's SHIELD portable gaming system. An AnTuTu benchmark was found for a device called, "NVIDIA test model(SHIELD)" with an "NVIDIA Gefroce(Kepler Graphics)" GPU, typos left as-is. My gut expects that it is valid, but I hesitate to vouch the rumor. If it even came from NVIDIA, which the improper spelling and capitalization of "GeForce" calls into question, it could easily be an internal prototype and maybe even incorrectly given the "SHIELD" (which is properly spelled and capitalized) label.
Image Credit: AnTuTu.com
As far as its camera listing, it would make sense for the SHIELD to get one at standard definition (0.3MP -- probably 640x480). The fact that the original SHIELD shipped without any, at all, still confuses me. The low resolution sensor still does not make sense, seeming like an almost pointless upgrade, but it could be used by NVIDIA for a specific application or built-in purpose.
Or, it could be an irrelevant benchmark listing.
Either way, there are rumors floating around about a SHIELD 2 being announced at E3 in June. It is unlikely that NVIDIA will give up on the handheld any time soon. Whether that means new hardware, versus more software updates, is anyone's guess. The Tegra K1 would have been a good launching SoC for the SHIELD, however, with its full OpenGL 4.4 and compute support (the hardware supports up to OpenCL 1.2 although driver support will apparently be "based on customer needs". PDF - page 8).
Waiting. Seeing. You know the drill.

The five most noteworthy Jetson TK1 breakthroughs may get a chance to share their work at the NVIDIA GPU Technology Conference in 2015.
AM1 Walks New Ground
After Josh's initial review of the AMD AM1 Platform and the Athlon 5350, we received a few requests to look at gaming performance with a discrete GPU installed. Even though this platform isn't being aimed at gamers looking to play demanding titles, we started to investigate this setup anyway.
While Josh liked the ASUS AM1I-A Mini ITX motherboard he used in his review, with only a x1 PCI-E slot it would be less than ideal for this situation.
Luckily we had the Gigabyte AM1M-S2H Micro ATX motherboard, which features a full length PCI-E x16 slot, as well as 2 x1 slots.
Don't be mistaken by the shape of the slot though, the AM1 chipset still only offers 4 lanes of PCI-Express 2.0. This, of course, means that the graphics card will not be running at full bandwidth. However, having the physical x16 slot makes it a lot easier to physically connect a discrete GPU, without having to worry about those ribbon cables that miners use.
