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.

Then there are games like deus ex hr that the more cpu you give it, the more fps.

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. Once you get enough cpu power, the fps are the same.
