problems with the Ati diamond viper x1300

I just bought a ATI diamond viper x1300 256 pci (yeah it sucks but thats all i can get) and before i had a bfg nividia 6200 geforce fx oc and GW ran fine with everything on high, then i bought, installed, and overclocked the x1300 and then GW fps dropped down to 3-5fps?? Its not because of the overclocking or the video card because i have games like Hitman blood money, Bf2 and fear which all run good on high-meduim bu yet Gw refuses to run good. PLEASE HELP i just bought nightfall and i dont wanna have to re-install my old video card eveytime i wanna play Gw

I'm confused! If you could run it well at high settings why would you take a step backwards? The BFG 6200 OC is probably the best PCI card with DX9 compatibility that you can get, so why have you gone and brought an inferior replacement?

no the x1300 is WAAAYYYY better it fully suports dx9 and shader 3 plus the core can be overclocked to 533, memory to 750!!!!!! That blows the 6200 out of the water. The x1300 can score almost 2000 more marks in 3DMark2001SE which yeah pretty much sums it up

The BFG 6200 OC also supports DX9 and SM3.0 and is the better card of the two, despite it's 64bit interface. Quite frankly if you're really running that X1300's core at 533 without any extra cooling solutions then you're just asking for trouble.

However, you seem to know best so with that in mind I wish you good luck.
