I played it aswell with a X2 " 2.3GHz and a mildly overclocked 8800GTS320 and it played in DX10 with all options on high as smooth as silk. Never had a problem anywhere with unacceptable framedrops! Works like a charm if you asked me!
But I couldnŽt get AA to work thourhg the Control Panel. IŽll try again though
