I'm currently using a 3GHz E2160 with 2GB RAM, and I don't seem to be coming close to running out of RAM in XP Pro, 32 bit. I'm considering changing to Vista x64 (so I can add another 4GB RAM when it gets cheap enough), and was wondering if I'd still be able to game with just 2GB. Should I go for it, or will it be bad enough that I should wait till I get the RAM?
