No, it will play the game though, probably on fairly low to medium settings. Having a slim pc for gaming is going to limit you to slower cards and you should be careful because of heat inside your case too, what card do you have now? and is there an open pci express slot in your computer?if there is a slot open the card posted by atomic rooster is probably your best choice.
Just saw your edit go with the 9800, probably your best choice.
