As I was shopping for my first gaming gpu last night, still unable to make up my mind between red and green, I got sidetracked (again)...
I stumbled on a very very cool video presentation from AMD about a tool called GPU PerfStudio.
I don't know why, but right after that I got an urge to learn about OpenGL, writing shaders, and got more interested in GPUs.
This might help the guys with the technical know-how (or those adventurous enough) to diagnose what is going on...
