don't get the fx5900, for that much money get ati 9800pro or xt. or better shot get one of the newest 6600 series they're cheaper then 6800's but i'm not quite sure if they've agp version, i think they do anyways i suggest u look at http://www.tomshardware.com/graphic/20041004/index.html http://www.tomshardware.com/graphic/20041222/index.html before making any decisions on graphics cards.. i suggest u to get ram & graphics card. also come to think about it check if u have spyware, virus, too many apps running, too many start-up items. etc stuff like that.. defrag as well then decide..
