I have this weird problem. during benchmarking of my 5970 i noticed that Gpu2 Usuage is 0% while the first gpu reaches usually 99%... the pc recognize the second gpu so i dont think it's dead or something... I reinstalled amd last drivers and it still doesnt work. Could it be during insufficient electric power? (I have Thermaltake litepower 700W)
HELP

Crossfire bridge installed?
What driver version?
What's the rest of the system?
