OK I just got my NVIDIA Geforce 7900 GT. Steps: 1) Uninstalled ATI Raedon x300 XPRESS Series (came with the computer) 2) Turned off the computer and inserted the Nvidia Geforce card in (it's a XFX btw) like the manual said 3) Started it back up and installed the drivers 4) Went to 'Setup' (when startin the PC) and changed Video Mode to PCI-E and disabled all BIOs except the sound I go to start a game to test it out and I still get the same FPS. I wouldn't expect to get the same FPS as I did with the integrated graphics so I'm stuck and confused to why it's (exactly) the same FPS. I have checked my display adapters and I only see "NVIDIA Geforce 7900 GT" and it seems to recognize it's installed correctly. Comp. Specs: AMD Athlon Windows XP 512MB I'm probably going to build a new computer from scratch with this card LATER on but right now I want to use this with this computer.
