I have a 7950 GX2 in my system currently and need a replacement due to it being on its way out. Started to get a dozen or so flashing pixels and it freezes on windows startup, only way i can get my PC to work is by disabling the drivers. Since i don't use the PC to play games much i am only looking to spend around £40, what do you think about the XFX GF 9800GT? or is there anything better for the price?
