Don't worry about your cpu when it comes to games unless you play at like 800x600 res.
Crysis Warhead is CPU bottlenecked on my system at maximum Enthusiast 2560 x 1440 8xAA. Disabling one the the cards and running in 2x mode makes virtually no difference in the gameplay framerate, only in unplayable cutscenes.
Stuff that I always assumed was purely GPU limited, like the SF4 benchmark, also seems to hit a wall at around 300fps. Running in 2x mode made little difference.
I guess that's what happens when you spend $1500+ on GPUs and $300 on a CPU.
...Which is at the top of that chart, oddly...
I posted my result a few weeks ago, but I don't think the list has been updated in a while.
P10462 - EVGA GTX 680 - 132%/+160/+560 - i7 950 @ 4.0ghz - 12GB @ 1600 - ASUS Rampage Formula III - Revolutionary - Air - Link
It's an awesome card.
Interesting...
Compared to Sketch's 3x 680 rig, his FPS is about 2.5-2.6x highter.
Compared to Kit Airwave's (higher clocked) single 7970, my scores are about 2.8x higher.
Does CFX now scale better than SLI? Did AMD actually do something right?
