AGP X1950xt vs AGP HD4670 1gb

Hello,
I am attempting to upgrade an old AGP machine with 1gb RAM running WIN XP PRO that currently houses an X1950xt 512mb that has since started to have multiple memory failures. I bought the HIS IceQ HD4670, and after what I considered a successful install of the HD4670, I saw that my PC was running a tad slower with opening, closing and manipulating Internet Explorer seems slower, (( moving windows around the screen shows tearing and lag )) and when running games such as Counterstrike Source, and TF2, the framerates have gone from roughly 120fps in 1920 x 1600 ( i think that was the res ) all the way down to 44fps with less effects turned on. I got these fps scores using Coutnerstrikes Video Stress Test and ran them several times just to make sure. So my question is, have I done something wrong installing this card? Is my 500w power supply not enough? Should this card be faster then my x1950xt ?? Or should I dust it back off, reinstall it, and RMA my HD4670??

Any help would be greatly appreciated.

I would assume the HD 4670 and X1950XT should be comparable.

Try uninstalling the video drivers in Safe Mode, then install the latest driveres.

Gave it a shot... no dice... and the version of the x1950 I have is the pro... not the xt like I thought.... In any case... the 1950 still seems to be outperforming the 4670 by about 300%.... Is there anything else I could possibly be doing wrong???

Well I think Im just going to RMA the card, and save up for a new rig... I will probably just take the latest issue of PC gamer and piece together what they consider the top of the line
