Intel graphics are worthless. You'll be able to use 1xIR in some games, but my belief is that no one should ever buy a machine with Intel graphics if they intend to play games, period. As far as the processors go, you'll be able to play some games decently well (as long as you don't overheat) but most of the games you mentioned are going to need more power (4.0GHz or more).
