I am looking to get a new iMac 24". My wife uses it mostly to surf the net and play games and some minor photo editing. This Mac will have to last her a long time. I have already decided that I don't want the 3GHZ, the 2.8GHZ should be plenty for her. My question is do I want to spend the $150. for the NVIDIA 8800 video? My only concern here is she will want to play some games. She is not a "hardcore" gamer. I just don't want to find that she wants a game that will NOT run because I didn't get the fastest graphics.
