The performance deltas here are on the order of one to three frames per second. Basically so low that you can consider it even. There is a reason why CPU tests use low resolution game runs (mainly to test the memory subsystem). As has been known, running games at the level people actually play them at has little to do with CPU performance.
Pretty much any modern CPU can easily handle any game out there. This just goes to reinforce that. If AMD's inferior Deneb chips can keep pace with Bloomfield or Lynnfield chips in gaming, but get battered badly in CPU intensive tasks, it's obvious that most games don't hit the CPU very heavily.
If you're ONLY going to be gaming and never plan to, for example, rip a DVD to H.264 or compress large .rar files, then you'd be fine with a less powerful CPU. However, if you actually do any sort of semi-productive work on your PC then you're better off with intel processors.
