Bro... 6fps for x1650? that is way way tooo low... i had a similar specs of ur com last time. i get around 30~40 fps.. very smooth gaming.. even when i go Pvping also no prob... above medium settings.

I have two friends still using 9600pro for the game... still running smooth.. stable at 20fps+ and again P4 2.4ghz only old skool machine..

Maybe your girlfriend did not update her driver, not using the correct driver or maybe she is not using any driver at all? hmm...

MY cpu was a P4 2.8ghz, ram was 1gb only. running on a X1650 pro, and 19 inch running on 1280 x 1024. Did u try running on a lower resolution? have u tried playing other games? like counterstrike? go try 1.6 counter strike and look at the fps, if the fps is too low, it's mostly ur gf have a faulty graphic card. but yet, there are a lot of other factors.. u can also try lowering the graphic settings, or reformat the computer.
