its a note book gfx card and no, it wont match the quality of the ps3... it will barley run the game on minimum as the 6630m ist as strong as an 88gt and thats minimum recommendation... your gonna be lucky to hit 4 fps at absolute minimum settings and rez gounf by the bench results i have linked.
its 1 thing to want to play games on a laptop. but to try on a mac ?
the sad fact is that if you had of spent half the money on a acer or similar you would probably be able to run the game.http://www.notebookcheck.net/AMD-Radeon-HD-6630M.43963.0.html
