the 6950 is a good swop.. You can easily get a aftermarket cooler for about R500 odd and then flash the bios to a 6970 .. Expect about 20% + Performance increase
My mate gave me the card last night to test and to see if I want to trade it.. I have the card in my pc and I have been testing it since last night. The card seems perfect. I even did 3d Benchmark.
