Hey, maybe this has been asked specifically but I've been looking through the forums and I see a lot of different opinions. I've got a 2.2 MBP that I want to put windows on for gaming and whatnot. Right now I have the standard 2gb of memory but I'm going to upgrade it to 4. In this sense should I look at getting a 64 bit version to take full advantage of it? Now apparently there's issues with drivers, how hard is it to find and install most of the drivers I would need? The other question is vista or xp? The consensus seems to be xp for games and stability. But if I plan on using this notebook for say 2-4 years would I be better off futureproofing myself by getting vista or will xp be sufficient? Any advice is appreciated as I'm not that computer savvy.
