I have a Dell Studio 15 1555 running an Intel P8600 2.4GHz duel core, 3GB DDR2 RAM and a Radeon HD4570 running at 1366x768 res. The game plays fairly well with everything on medium without AA and at my highest possible res. Sometimes it does lag out though so I knocked everything down to low except car detail just to go a little easier on my aging laptop. I'll have my new PC as soon as they fix Sandybridge anyway so gaming graphics isn't a huge thing for me right now, just as long as I can play the game i'm happy, the cars look pretty nice on medium anyway.
