I would say that it will be able to run almost every game out there right now (not at very high settings, but still). The reason I say this is because I used to have a Dell i6000 with a x300 in it. That one had 128mb dedicated VRAM. It kind of sucks that the 1150 will use up 512mb of system RAM, but it should perform on par with what I had. To give you an idea, I was able to play BF2 (at pretty low settings), Rome: Total War (+ BI) (full settings), NWN (full settings), BG2 (full settings), and a couple of other games, with no problems.
