I picked up a high end gaming rig this year i7 on the new Asus Sabertooth 97 motherboard with a couple ssd and 16 gb of ram and a video card that I paid way to much for. I started out with Windows 8 but went back to 7 and i was told windows 8 was faster in gaming but I couldn't see any difference at all. I think when you have a hi end rig there is no difference.
