Minimum specs for the game call for an Athlon X2 4800+. Your card matches the Radeon HD 3850 512MB, so your graphics card would just barely meet the minimum requirements. 2GB of RAM is also quite low for running just about any modern game on Windows 7. The game might run okay at the lowest possible settings, but I wouldn't count on it. If possible see if there is a demo and try it out and see if it runs acceptably.
