So I am super excited that my 8 core 2.8 is arriving on Monday with the 8800 GT card installed. I was able to snag a copy of Vista Ultimate and wanted to try out some gaming. Right now I only have 2 GB of RAM but will be bumping it up to 10 GB in the near future. My question is this: Why not go Vista 64? Apple says that I should only install 32 but why? Are there advantages to 32 I don't know about or do some things not work right in 64? I am not worried about drivers for my printer, scanner, or anything else because the Windows partition is for gaming only. Thanks for any insights others might have.
