So, I decided to mess around with OCing my video card. MSI R6850 Cyclone PE/OC Radeon HD 6850 1GB 256-bit... First thing I did was run a Heaven benchmark to see what the numbers were stock. After running Heaven I thought it seemed very low and looked back at the one I ran when I first built the computer. I was surprised at the difference in numbers. The only thing that I have done since building this rig is updated the drivers. Could that be why the score is so much lower now? Should I try the older driver? If so, where is the best place to find older drivers?
