Windows 7 is better optimized for games so you should get more FPS in 7 that you would in XP.
Lets not take a step back here. XP is over a decade old, let's keep with the times and use 7, it's great!

I don't think there was much difference with CoD4 when I moved from Vista to 7. Same hardware anyways.
Well, of course there was a difference as my Vista was so cluttered, but nothing significant. I hope you understand my point. :D
