Hi, I've got a kick-ass 8-core mac pro and now I've come across a dilemma The problem is, I'm trying to run GTA IV but it's just painfully slow through Boot Camp on my XP SP3 x32. I've got a licensed Vista x64 disk, and I am thinking about using it. Can the regulars here recommend it or not? Do you think I'll have a better gaming experience? PS. - I'm not using x32 Vista on my Mac because as I go into a game or even watch a Youtube video, the sound glitches and slows for a few seconds.
