I recently purchased an upgrade for my outdated system that Tom's
Hardware had an article on, the Gigabyte ATI Radeon HD 4650 1GB GDDR2.
Please keep in mind that this is an AGP card.

First I will give you the stats:

MOBO: DFI 875P-T (Phoenix Award BIOS never updated since purchase)
with an upgraded bios chip to support my processor
CPU: Pentium 4 3.2 GHz.
Memory: 2GB
HD: 320 Gb Seagate Baracuda 7200 RPM 3.0Gb/Sec xfer speed
GPU: Gigabyte ATI Radeon HD 4650 1GB GDDR2 (GV-R465D2-1GI)

I was running the Radeon x900 xt platinum edition previous to my
upgrade. If you need me to fetch further specs, I can do so.

Anyhow I opened up my case, dusted it out (esp around the AGP slot),
took out the x900xt, dusted again, and installed the 4650. I made
sure the power cords where also plugged in. I updated to the most
recent drivers (still the ones on the CD) and fired up the infamous
WoW. I did not change my video settings from what they were with my
last GPU. The game runs choppy as hell. GPU LAG EVERYWHERE!!! Given
that this is an old system I am not sure if I needed to do anything
beyond installing the card and updating the drivers. I am running all
the ATI utilities as well. I havent tweaked anything.

Anyone have any idea what is going on? This card should leave my old
card in the dust. Obviously it isn't going be able to play GWAR on
max settings, but I just want to play WoW and Titan Quest on normal

Edit: I also tried installing old drivers. This didn't help.
I also uninstalled the GPU, resprayed the slot, double checked the power connections, and reinstalled the card.

Did you UNinstall the video card drivers before you swapped out the cards? You need to UNINSTALL the drivers before you swap them out. YES, even if they are the same 'brand' (ATI)
And I'm guessing your old card was a x1900 xt? ATI ?
Take a look at this chart and you will see a 4650 is not much of an upgrade over a x1900. (if that's what you meant in the first place)

The only problem I'm seeing is if you were to swap that for maybe a 4850/4770 or something better it's goin to be held back by your processor in the end.. What resolution are you playing at?

Did you reinstall the game? maybe it needs to configure itself to your new component.
