Basically the title says it all.
I have 4GB of ram on my new build. I had installed XP Pro 64 on a previous system with 4GB but I had some problems with programs working/installing on the XP Pro 64. I built this new comp for Crysis and other high end games. I would like X10 support so i can play Very High on Crysis. I know there are limitations on 32 bit OS but would I see a huge decrease in performance if I installed normal XP with 4GB (i think it can only use 3.5GB) vs Vista or the 64 bit versions?
