Thanks for your reply Bob. I am an old fart and sometimes don't completely understand it all. I guess a 1 GB would probably do the trick, it would double my current card and probably not overload my power supply. I just thought the price (about $80) wasn't bad and I hadn't seen that much memory before. Can you recommend a good lower priced card. I really don't want to spend a lot on a system that I will probably replace within a year or so. Again thanks for your reply and suggestions.
