Microsoft Announces Vista Hardware Requirements

[Tyler]

"Vista will run on just about any modern computer released in the past few years. An 800MHz processor coupled with 512MB of RAM is the bare minimum for running Vista. You won't get all of the fancy graphical enhancements and you most likely won't have a very pleasant experience performance wise either. For me, it's bad enough running a Windows XP system with a lot of windows open that is "crippled" with just 512MB of RAM (between Photoshop, FireFox and its memory leaks and the countless other programs I run), so I couldn't imagine limping around on Vista with only 512MB."
