I have two 7850s and I don't really have any issues. Just a bit weird gpu usages, meaning the second card is showing 99% all the time, even when the game is minimized. I guess that's some sort of a bug. And the 1st card is used about 50% or something.

In crowded areas everybody is getting huge fps drops, no matter if it's a single 7850 or gtx 780 sli or whatever. I read someones post who mentioned that it's most likely due to current dx9 limitations which makes some of the "advanced" graphic effects heavily tax the cpu, at that point it doesn't really matter what gpu you have when you are bottlenecked by gpu->cpu->gpu or something. Hopefully we'll see better performance with the dx11 client.
If you have Firefox open, than that is the problem. It's a bug where the drivers continue using 100% to render Firefox tabs. Close it, or disable hardware acceleration in Firefox.
