i rma my 4850 so as a temp card i got an gt 220 1024 ddr2 is seems to run left 4 dead 2 fine but has started to slow down so i am thing the cheap card is just defective, i found a TurboCache GeForce 9600 GSO 512MB i am thinking of picking up but it has the same amount of Stream Processors 48 and so dose the gt 220 so there would be no difference
