Windows? yuck.. you can bootcamp all you want....
I'd rather play something in OSX even if it was only half the performance.
I NEVER sit and just play a game without doing other things... Lose my whole OS and all my software while playing a game? I'd rather just not play.
Well...since you don't care much about performance anyway...then just VM it. lol Not sure if DX10 works in that mode.
