Importance of CPU in high-end gaming

Once you reach the point where games start to require the best in video graphics like METRO 2033 or Crysis 2 whether because it is necessary for the complete visual experience or simply because it is poorly optimized, does CPU strength still play as big a role in smooth performance? I don't mean bottlenecking but for instance, would the performance from a GTX 580 and an i5-2500k versus a GTX 580 paired with an i7-980x really be roughly the same or minimally different?

Roughly the same as the games tend to demand much more from the GPU than the CPU. An i5-2500 or the i7 would not be bottle necked even at stock clocks.

It'll be the same. Once you have a cpu with enough power, the gpu becomes the limiting factor on your fps so in a sense is a bottleneck. But it really depends on the game, Metro is very gpu intensive and there are even games like AVP that could care less about cpu. http://www.tomshardware.com/reviews/sandy-bridge-core-i...

Then there are games like deus ex hr that the more cpu you give it, the more fps. http://www.tomshardware.com/reviews/deus-ex-human-revol...

Games like metro and crysis are the common benchmark games because they require a lot of gpu power but still enough cpu power to get the full potential of the gpu. http://www.tomshardware.com/reviews/sandy-bridge-core-i... Once you get enough cpu power, the fps are the same.
