New Graphics Card with New Problems

[Jaebird]

I recently bought an nVidia GeForce 8400 GS 512 MB DDR2 PCI card, and after installation, my framerate dropped substantially while playing World of Warcraft when compared to using the on-board graphics (nVidia GeForce 6150 SE).

When I played another game, such as Team Fortress 2, its the exact opposite situation. I tweaked every setting there is to be tweaked, and the results are the same every time. Am I missing or overlooking something, or should I see about getting a PCI-Express card?

My PC specs:
Windows Vista Home Premium
AMD Athlon 64 x2 Dual Core 5000 (2.60 GHz)
3 GB RAM
32-bit Operating System

Are your drivers up-to-date?

Ensure that you have disabled your onboard chip. Although normally this just causes an outright error. Update your drivers as well.

If his onboard was enabled, he wouldn't be able to see his game, as the monitor SHOULD be plugged into the new video card...

You know, unless he installed the new vid card, and hooked the monitor to the onboard...
I don't deal with onboard graphic cards much (really, who wants to? ) so even if it were enabled it shouldn't really be slowing much of anything down... right?

Out of curiousity, did the OP Uninstall his OLD drivers before installing the new ones?
Did he use the factory shipped cd that came with the vid card?
Have you Updated your Motherboard Drivers?
Have you updated yoru Bios?
Have you checked your bios to make sure its running the AGP/PCI video card correctly?

I know I recently had an issue with another computer of mine, wierd ass video bugs going on. DRivers were uptodate, card 'should' have been fine.
Turned out, when I went to the motherboards website, there was an AGP driver (did I mention the vid card was AGP?) Basically missing that one driver, screwed up the way the vid card interacted with the mobo...
You'd think when they do motherboard drivers, they'd like... you know, include AGP drivers in the fucking mobodriver!
