ICE -
If my eyes don't deceive me, that's actually a PCI card and not PCI express.
If that's the case, check to see if you have either a PCI Express or an AGP slot and look for either of those two other options. If you're stuck with the PCI, congratulations on being a survivor of a dying breed. You might want to try Newegg or Zipzoomfly, where you can get the same card significantly cheaper ... and also where you could purchase a cheap, new motherboard, as well
