dude for only $100 dollars i cant find anything better than that 9800xt you have. for $100 you cant really get anythign good from nvidia. go ati if you have 100. I say just buy the 9800xt. Although you best bet would be to get the 6800GS in agp: http://www.newegg.com/Product/Product.asp?Item=N82E16814130002
