Neither of those games require much horsepower. You could probably get a used 6800GT AGP for cheap and it "should" run both of those games at max detail settings @ 1600x1200 or so. If you want more power, there are x1950XTs in circulation, I think that the x1950XT AGP is one of the most powerful AGP cards (but, my knowledge is a bit dated). The x1950XT would be overkill for both WoW and WC3.
