I am building a completely new (also my first) gaming rig. I think I have most of the specs finalized, but I am having difficulty choosing an OS. My question is which OS to choose, windows 7 or windows 8.1? I have heard there are some minor performance increases (boot times especially w/ and ssd [duh?] ). I have limited experience with windows 8 but extensive windows 7 experience. I am very happy with windows 7 but because this is a completely new build is it worth the extra 8 bucks or whatever it is to buy windows 8.1 vs win 7?
