Look, you're not going to enjoy Crysis on that thing (it would struggle with medium), but it should be enough for some light gaming. If you're just gonna play the sims it will be fine. If you want to play MWF2 or Black Ops though you may be dissapointed at having to use lower quality settings depending on your resolution.
If you want to game on your laptop I would recommend getting something with a nVidia 360M or Radeon 5700M though you can get something better if you're willing to spend more. If that's out of your budget then at least go with a 330M (a faster clocked version of the 325) or Radeon 5650.
