I've been holding off on getting Mass Effect 2 because I didn't think my computer could handle it(I had issues with freezing on Mass Effect 1 that I'm now wondering if they may have been due to some bug), but anyway, I was looking at systems requirements, and I think the card listed as the minimum might in fact be what I have.
Now I need to go home and check, but I don't get out of work for over four more hours.
