@mb_webguy, I don't even have 4GB RAm, as I took my computer in a few weeks ago to see if I cou8ld add RAM (I wanted at least 3GB RAM to try and run AutoCAd, but was told I and barely 2? and also it wasn't even upgradeable as there wasn't a spot for that (it's what the guy said). After going back and forth and reading all the posts (and what the computer shop guy said) I think I will go with the 32 bit. It probably could handle 64..but just barely lol. I think it might be a strange computer as I had some little ol guy at a now closed computer shop build it for me about 4 years ago. Some day I would like to build one for myself, should be interesting.
