Benchmark Results: Left 4 Dead
2560x1600 is probably the only resolution that matters when testing $1,000+ graphics solutions, and that’s where two HD 4870 X2 graphics cards in CrossFireX take over. We once again see what appears to be a CPU performance cap in a four-GPU solution, but this time it’s the two GTX 295 units taking the hit.
The GTX 280 3-way SLI configuration adds the 2560x1600 resolution to its overall performance lead, once AA and AF are enabled in Left 4 Dead. The GTX 295 Quad-SLI performance cap is alleviated at the highest setting, simply because its GPU load finally exceeds system load.
I would have liked to have seen some temperatures in there somewhere as well. With top end cards becoming hotter and hotter (at least with ATI) I wonder if cheaper cases are able to cope with the temperatures these components generate.
BTW any chance of doing some sextuple SLI GTX295 on the old Intel Skulltrail?
Not a chance: The GTX 295 only has one SLI bridge connector. NVIDIA designs its products intentionally to only support a maximum of four graphics cores, and in doing so eliminates the need to make its drivers support more.
ie. a big 3x3x9" box resting on the expansion slots, dumping warm air outside.
thrown." --> "throne"? or am I just misunderstanding the sentence?
Congrats on quad-sli, though, for anything that doesnt already get 100+ fps with a single GX2, you're welcome to throw in a second and get at most a 10-20% increase, unless of course you want to get an increase to a game that doesnt already have 100 FPS (crysis), in which case you're screwed - dont even bother with it.
And I'm a little disappointed with the scaling of all solutions. They still don't scale well.
