GeForce 8400GS PCI

Hi, I recently got a GeForce 8400GS PCI 512 DDR2 for my spare machine. The spare machine is a Dell Dimension 9100. I am trying to find out if this video card is an upgrade from the stock PCI-Express card and if it is, will I need a better psu? I know the Dell Dimension runs a 350 psu, and I believe that to be efficient.

I have already installed it and it seems to run the only game played on this machine (World of Warcraft) less efficiently than the stock card. Even on the lowest setting the game still plays choppy. Any information will help me out a lot!

  1. You haven't told us what your stock card is...
  2. According to Device Manager I am running an ATI Radeon x300/x550/x1050. Hope this helps.
  3. I would use drive cleaner pro(a free download) to make sure all remnants of ati drivers are gone, unistall the nvidia drivers(may as well start free) download the latest drivers from nvidia and install again, that should fix it.
  4. But is the GeForce PCI card better then the ATI PCI-express card?
