|The release of the GeForce 9800 GX2 marks the (probable) return of Quad-SLI and although Nvidia hasn't said anything about it, a few people around the world just wanted to see it at work. First up, the guys at TweakTown have toiled into the night to test a GeForce 9800 GX2 Quad-SLI setup and, as you might think, the results are all over the place.
Hooked up to a system consisting of an nForce 780i board, a 4GHz-clocked QX9650 CPU and running 64bit Vista and the newly-released ForceWare 174.53s, the two GeForce 9800 GX2s have managed to return significantly higher scores in Crysis but it didn't impress in Unreal Tournament III where a single 9800 GX2 was faster or in 3DMark06. The full results can be viewed here.
The second Quad-SLI article has been posted by vga.zol.com.cn and it sees the two G92-powered 9800 GX2 tested with a 3.2 GHz QX9770 system loaded with the 174.53 ForceWare drivers and 32bit Windows Vista Ultimate.
The results showcased by this review paint a picture in which the Quad-SLI setup offers notable performance gains in Call of Duty 4, Assasin's Creed, Company of Heroes and Crysis. Low or next to none gains have been seen with World in Conflict, Gears of War, Bioshock or TimeShift. The pretty colored graphs with the actual numbers can be found here. Overall, we can see Quad-SLI performance being very game dependent, which is not surprising. With results varying so much Nvidia probably wants to officially re-introduce Quad-SLI when it has a new driver.
