But, more to the point. This morning I ran Metro 2033 benchmark. I got 22fps on High. That was using GPU1 30% and GPU2 98%. So, I swapped the cards over in the slots. Ran the benchmark again and got 46fps GPU1 98%, GPU2 78%. So everything is running great again.
So my problem is everything will be great for a few days. Then I'll have to open the case and swap the cards over in the slots again. I have no idea why this happens and whether its a HyperSli thing, a crossfire issue (because when I google it, this happens with Crossfire more than SLI it seems and it is a crossfire board). Or are the Nvidia drivers just useless at picking out the primary GPU?

Right... Rage is a non SLI game, better kombustor to see if it works.
