i was about to preorder windows 7 for my macbook pro 4,1 with the student discount and cant figure which of them to get. I've messed around with vista 64 bit and was never able to get all the drivers working even after downloading a custom drivers pack by someone else. I heard windows 7 was pretty good at identifying necessary drivers. At the moment I'm using windows xp 32 bit. I really want 64 bit to take full advantage of my 4gb or RAM. any suggestions?
