I'm going to dual boot either Windows 8 Consumer preview or Ubuntu on my Mac. I would rather do Ubuntu because I like the UI a lot better, but if my games don't work then I'll use Windows. So can I play my Steam/Origin games (Battlefield 3, MW2, MW3) in Linux? Will they perform like crap compared to if I did it on Windows? If I can't use Ubuntu, should I use Windows 7 or 8? Thanks.
