new graphics card installed and now BF is jerky

[Colder]

i just bought the Radeon X800GTO GDDR3 256mb AGP 4x/8x video card and installed, updated to the cat 6.1 driver off of the ati website, and now when i load and play BF2 and BF2 SF it's really choppy, like i'm getting serious lag, but my ping never went on 60 on the servers i was playing on. I need help.

system specs are as follows:

CPU: AMB Althon 64 3400+
GPU: stated above
Memory: 2 gig Corsair XMS
OS: WinXP Pro
HDD: 250gig

Any thoughts would be greatly appreciated.

what videocard did you have prior? and what brand of power supply do you have?

had the ati 9800 pro 256 (it burnt out on me) with a thermaltake 450 watt powersupply

did u make sure to uninstall the old drivers and the old video card with like add/remove hardware and add/remove programs (im not familiar with ati, but with nvidia all u need to do is uninstall the drivers)

also make sure to delete the bf2 cache files, they probably need to be reset cause of your new card. I acctually had to reinstall BF2 when i upgraded my video card to make it work right.
