I'm running the game on a 6200 right now (I have an 8800GT in my real gaming comp, but the motherboard was defective and fried itself, so I'm on my brother's old computer until Asus sends me my replacement), and my game invariably crashes. It's worst with the latest video drivers (rolling back lets me play for 5-10 minutes before my system restarts itself, as opposed to the 1-2 minutes I get with current video drivers), but not working well by any measure. I'm running a 2.8 Ghz CPU with 1 gig of RAM, so if you have a similar system you may want to wait for the demo and/or a new patch. I want to play this game so badly, but the five-minute increments of playability between reboots are driving me nuts.
