Im considering upgrading my old AGP 9600 PRO card to a newer and faster AGP video card and i was thinking one from the X800 family and yet there are a few types and i am unsure as to which one of them is most likey the best. My budget is around $250 Australian Dollars so i don't know what you guys use here ($US?) but if you can suggest whether the X800XT, X800XL or X800 GTO is the better card? maybe these are the same cards and im being an imbecile but if you could let me know it would be great. Im open to cards that are in the same price range as these and may perform better. Any help would be greatly appreciated, thanks guys.
