I'd say it depends mainly on your OS. If you're running XP or Windows 7 I'd say the game will run fine. If you're running Vista you'll probably experience some slowdowns here and there and loading times may be a bit slower, but overall performance should still be fairly good.
edit: to kyle - ME2 doesn't seem to support single-core processors at all, so that'll be the root cause of your problem. There are some threads out there on how to improve the performance a bit, but I doubt you'll ever get it to run well without upgrading to at least a dual-core.
