How is Vista? I have a computer at home that I think will run it at a usable level, but I'm not sure if I should keep using XP pro, or upgrade with the intent of being future compatible. My home computer is: P4 HT 3.06 2GB DDR2 533 256mb Radeon x330 250GB SATA HD I know it meets the requirements, but it seems like systems have gotten way faster since I built this computer. I'm just really wondering if it would be horrifically slow. I would probably be getting a basic version, even though the Ultimate is what I really want, but that almost $400 price tag isn't something I would be able to pony up with school starting. I guess a sub question would be, is it worth picking up a 64bit version if my board only supports 2GB of ram? Are there any other benefits to an average user than utilization of more memory?
