Well there are some mouse lag issues, but there are fixes to most. I think windows 8 is good for 6-8 core processors, because it utilizes more cores.
If you have quad core i would stick with windows 7, but i heard on some articles that BF4 plays smoother on the windows 8.
I'm thinking about a quad core processor (Intel i5). My father suggests I go for Windows 8 as he doesn't want to buy an OS which is one generation old. However, I say that according to what I've heard, it is a bad OS for gaming. As a whole, would you that the overall experience in gaming would be better in Win 8 or Win 7?
