And to the fella who said I am an Nvidia fanboy, just look in my sig I also made a huge thread about 5870 OC'ing in this very forum, and about 2 or 3 big threads regarding HD5870 launch/speculation. I LOVE ATI. Now, continuing on...

It also appears the op doesn't have CF enabled and running properly when he states the "main gpu runs at 66% in dalaran and the second gpu stays at 0%". Maybe the crossfire mode/profile forcer will help you out. It gives you the option to force 4 different modes of multi-gpu rendering that you could test until you find the fastest one. Instead of decreasing all your rendering quality options to the "performance" mode. You might consider just lowering shadow detail for when you're raiding and 1000 characters are on screen.
