Your laptop should be able to run the game fairly well. My laptop has a core i5 450M and a geforce 310M and I can push about 20ish frames in low populated areas with low-medium settings on the newest beta drivers from nvidia for my GPU (334.67). An i7 and 435m should be able to push quite a bit more than my crappy laptop. That said, the lowest settings on PC (aside from shadows) still looks better than the PS3 version. And you won't have the same frame rate limits set on NPC and other player character animations (it's choppy on the PS3 since they had to dumb it down with a very limited amount of RAM to work with).

I mainly play on PS3 because of my frame rate issues, but your laptop can likely play the game, if you don't get heat issues.
