Ok so i bought a Powercolor Radeon HD 6850 for a low price of 135$ and when i installed it on my rig to test it on a few games there was a problem... The worst possible thing that anyone could have is that.... I have no performance at all. Any game which i test lags to the point of where i can't even exit the game normally and have to alt+f4 or worse restart the PC. I can't think of anything that could cause all of this. I installed the drivers from the CD which came with the card and even updated the graphics drivers and no change. The card by the looks like its working fine, fans spinning, the temp is normal. I had no problems with my old geforce gt 240 1gb gddr5 which i have about 2 and a half years. I have a 550W PSU so that couldn't possibly be the problem or then again maybe it is since i bought it in 2009 with my GT 240. My other specs are: AMD Athlon II X3 450 CPU 3.2 GHz
