I don't remember the specs off the top of my head, but my harddrive is fairly large, and the graphics card runs games like Rome Total War, Medieval TW, Fleet Command, Shogun Total War and Destroyer Command fairly well, but I do turn down the options on the graphics just to be on the safe side. I do have some memory issues with RTW, but nothing serious. I can't run the more advanced games like Medieval2TW, Silent Hunter 4 and any of the graphics heavy FPS', but I didn't have built for gaming
so this isn't surprising.
