Final Vista Hardware Requirements

[Mercutio]

Here.

Graphics: A Radeon 9500 or Geforce 5200. Guess that means that if you can do DX9 you're OK.
RAM: 512MB minimum
CPU: I didn't look at Intel, but the low end AMD desktop chip is a Sempron not an AthlonXP.

I wonder if SocketA chips will even be a possibility.
