I just purchased my first Mac, a 21.5" iMac. Along with that, I ordered a copy of Parallels. So, you'll have to forgive me if it's a foolish question. My main question is this: My Mac has 8gbs of RAM. If I were to install XP32, would it be unstable? I know if I were to run XP32 on a Win machine with that much memory it would be. Would it be a better idea to track down a copy of XP64? Thanks.
