I just installed Vista Home Premium 32bit on my blackbook. The main reason was to play Left 4 Dead. I did some searching but I couldn't find anything. I have 4gb of memory that I put in it. The game still runs choppy. I'm aware the graphic card is the Intel 3100 and is not meant for gaming. Would it help if I installed a 64bit to get 4gb rather then 3gb on 32bit? Is there anyway I could overclock the 3100 at all? I realize that could be bad in the long run... Any ideas?! I want to upgrade to the new MBP, and I will in Juneish. Thanks.
