neither one are good compared to a geforce 6600 gt which is incidentally in the same price range,it will blow away both these cards in any benchmark or any game,go with 6600 gt blindly.other two cards are rally old,this is relatively very new has 12 pixel pipelines,shader model 3.0 full direct x9 support very fast memory interface,i mean there is just no comparing this with the other two it completely desamates all.think of playing doom3 at 60+fps with this one,dont believe than just read around on the audio video forum or check out any benchmark.its even recommended by thg as the best buy for a video card,check out tomshardware.com for more.
