I'm sorry I forgot to add that I already installed 1 gig of memory. Any newegg links or amazon would also be awesome. Thanks for the help.
Since your model only has PCI expansion slots, this kind of limits your choices.http://www.newegg.com/Product/Product.aspx...N82E16814187057
^- Updated video card for a PCI slot, may work well for you. Probably will run hot, so beware of that and have good airflow in the case if possible.http://www.newegg.com/Product/ProductList....amp;srchInDesc=http://www.amazon.com/EVGA-nVidia-e-GeForc...5011&sr=8-3
^- I've used this card, but in the PCI EXPRESS version. It is a low-end budget card, but I could run World of Warcraft just fine, even at 1920x1080 minus the drop in frame rate during really intensive fights. Recommend 1024x768 or as close to that resolution as possible. This card will NOT run higher end games like Team Fortress 2, etc...http://www.amazon.com/s/ref=nb_sb_noss?url...amp;x=0&y=0
^- Make sure you don't buy a PCI EXPRESS card and that it is a PCI card, as they don't have them separated in that search.
To be honest, however, with that old of a computer, you probably won't get that much throughput with your card in terms of frames per second so the game play will be marginal at best.
