Firstly I need to make something clear. I DO NOT PLAY COMPUTER GAMES!
I'm not in the slightest bit interested in producing a gazillion frames per second at a gazillion resolution.
All I need is smooth 24fps @ 1920 x 1080 on dual monitors using Sony vegas/Adobe Premier. (indie filmmaker)
I'm looking at used GPU's at my local CEX. They have a 9800 GX2 which is a hell of a step up from my old 7950 GX2 which has been sold along with my old bundle.
How will the 9800 fair? Apparently this was a flagship card a few years ago.
Antec 480w true
Seagate HD501LJ x 2
XP Pro 64bit
Samsung 2333SW x 2
i7 onboard graphics (frame rate drops to 20fps at high resolution)
