if the game is GPU limited, the performance should be the same on any CPU (given that is fast enough), the difference you see on that "Shogun 2" graphic is almost nothing, is withing a margin of error or irrelevance, like in any test limited by the GPU... if you add another (SLI, CF) or a faster VGA (or maybe lower the details) probably it can change things, because then the VGA is fast enough to not be the main limiting factor of the framerate,
keep in mind, that on the same game you can go from GPU limited to CPU limited quite easily, depending on the scene, the action, what's is happening, and how fast your CPU/GPU are.
here they tried to isolate a CPU limited scenario on the same game:
but unfortunately the FX crashed (as it did in this game in other 3 reviews or more)
but you can clearly see a difference, CPUs scaling with OC and so on, when in a GPU limited part of the game/settings you are not going to see this.
also you can see that the 2600 performance here is much lower, because they used a much more demanding (for the CPU) demo, and that's how you normally want to compare CPUs, not when they are irrelevant, or can't make any difference, because is more about how fast the VGA can run the thing.
if you test Crysis with a Radeon HD5450 performance will be around let's say 10fps, no matter what CPU you use (a Celeron or a i7 2700k), but now use a GTX 590, and the Celeron will run much slower than the i7
obviously on a much smaller scale, that's whats happening on that Shogun 2 graphic, the difference is irrelevant, the result is the same, and that's what the VGA is capable of on that case.
