like Vernong1992 said, the ram doesn't matter as much as the speed specs of the card. Look at the memory and core speeds of your current video card and the one you plan to get. as long as they go up, you should be set. Over the Geforce4, any of the cards listed by mousepad will improve things alot, but this assumes that you have a power supply that will support them. Would be easier to recommend compatible products if you listed specs of current computer as well.
