If you are a PC gaming and live near or around the Portland, OR area you are familiar with the concept of PDXLAN - one of the most popular (but still cool and underground) LAN events in the country.  The primary event is going on this weekend and I am here to both game and take a look at what the sponsors are showing off.

MSI has a lot of stuff going on including a look at the latest version of the Afterburner overclocking tool, the 3GB version of the GTX 580 Lightning (that Josh is currently working on a review of) and even a NVIDIA Surround based Dirt 3 sim seat.

Gaming laptops are still taking off here in the US and MSI has a couple on display including a HUGE 18-in mode (on the right) with a keyboard that lights up with various colors of LEDs, configurable.

The Sapphire guys are here as well and are showing off much of what AMD for gamers including Eyefinity configurations like the very popular 5x1 portrait mode.  This is something that only AMD offers currently and in this demo we were looking at Dragon Age II.  It was definitely grabbing some attention!

Showing that AMD's HD3D technology does indeed have legs Sapphire was showing off the new Samsung SyncMaster SA950 that has a nice external design.  I am going to spend some more time with it today to see how it performs, so check back for more!

If you are here, you can also find me getting butt kicked at various games.  This is the machine I'll be on, a Maingear built GTX 580 SLI right with an overclocked Intel Core i7 Sandy Bridge processor and 30-in display.  I know, it sucks to be me, but someone has to sacrifice and play on it, right?

More from PDXLAN later today!

Revisiting quad-gpus and the Law of Diminishing Returns

With SLI and CrossFire we all hoped to see direct scaling so that a quad GPU setup would be somewhere in the neighbourhood of 4x better than a single GPU.  That has proven to be incorrect, not only is the scaling nowhere near that it has been discovered that in some cases going beyond 2 GPUs can actually reduce performance.  

As the hardware and drivers evolve, it is worth revisiting the scaling performance of both AMD and NVIDIA which is why [H]ard|OCP grabbed two GeForce GTX 590s and two AMD Radeon HD 6990s, both dual GPU cards.  In three of the five games tested they ran into at least one issue, a strike right off the bat.  Read on to see how they rate the value of the two manufacturers based on the performance they saw once they'd resolved the problems.

"How does NVIDIA's GeForce GTX 590 SLI Quad-GPU compare to AMD's Radeon HD 6990 CrossFireX Quad-GPU? We will find out if these "if-money-didn't-matter dream video card setups" will deliver the gameplay experience we all expect."

Tri-Fire/SLI redux, look at the difference SandyBridge makes!

Subject: Graphics Cards, Processors | May 6, 2011 - 01:09 PM |
Tagged: tri-fire, crossfire, sli, triple, sandybridge

Not too long ago [H]ard|OCP examined the price to performance ratio between a triple SLI GTX580 system and a Tri-Fire HD6990 and HD6970 and discovered that as far as value goes, NVIDIA could not touch AMD.  A reader of theirs inquired if it was the aging Core i7-920 that was holding the cards back even with the overclock of 3.6GHz.  A SandyBridge system with a Core i7-2600K and an ASUS board with the NF200 bridge chip was used to revisit the performance of the two vendors GPUs.  The result; we can hardly wait for the Z68 boards to come out!

"We have re-tested performance between GTX 580 3-Way SLI and Radeon HD 6990+6970 Tri-Fire with a brand new Sandy Bridge 4.8GHz system. Our readers wanted to know if the CPU speed would improve performance and open up the potential of this triple-GPU performance beasts. To put it succinctly, they were right. The results completely turn the tables upside down and then some."

Which is better, three heads from NVIDIA or three from AMD

[H]ard|OCP just finished a review that most enthusiasts would sell their souls ... or at least cash in their retirement savings ... to do themselves.  They decided to find out which was better, a $1500 triple GTX 580 system or a $1100 HD 6990 + HD 6970 system.  The findings are really quite clear, as is th efact that scaling has improved to the point where dropping that third GPU into your PC actually does make some sense to do.

"We've seen what a Radeon HD 6990 can do when paired with a Radeon HD 6970 for "Tri-Fire" performance. Now it is time to find out what three NVIDIA GeForce GTX 580 video cards in 3-Way SLI game like in comparison. We will look at A2A performance comparisons and discuss which setup offers the best gameplay experience."

AMD 990FX, 990X and 970 chipsets to get NVIDIA SLI Support

Subject: Graphics Cards, Motherboards, Chipsets | April 28, 2011 - 09:45 AM |

In a move that is long overdue, NVIDIA's Tom Peteresen announced on a blog post that SLI multi-GPU support was finally going to be offered on AMD platforms with the upcoming launch of the AMD 990FX, 990X and 970 chipsets.  On previous AMD platforms users have not been able to use multiple NVIDIA graphics cards in SLI because NVIDIA simply did not allow licensing of the technology on them.  As of this month, that policy is changing.

According to the post, NVIDIA has had a change of heart and wants to "make sure gamers can benefit from the new CPU competitive landscape and ensure they have NVIDIA SLI – the highest performance, most stable multi-GPU solution - to game on!"  The lack of SLI on previous chipsets was the result of Intel being the dominate CPU platform of choice for gamers in recent years. 

ASUS, Gigabyte, ASRock, and MSI are going to be the first out of the block with motherboard based on the AMD 990FX, 990X and 970 chipsets with SLI support according to NVIDIA's Petersen.

This doesn't change NVIDIA's stance on the whole licensing and charging motherboard vendors to integrate SLI thing, however.  In an ideal world, NVIDIA would have announced that they were opening up SLI to work on ANY motherboard, future or present, that has enough PCI Express slots on them, just like we see today with AMD's own CrossFire technology.  Despite pressure to do that, NVIDIA is standing by its current formula and expanding into the realm of AMD chipsets.  

Regardless, today is a good day for AMD fans and gamers alike that want more choice and more variety in their system build options for the future.  The AMD Llano and Bulldozer-based processors just got a little more gaming friendly.
