Here's what I've gotten so far on a test rig, it's just 3 random cards (Sapphire 270x, Vapor 270x, AMD 7950) which usually does ~1.3 MH/s.
http://i.imgur.com/pqM9rJa.jpgI can probably get a little more, but no HW errors makes me happy! I'm glad I found this thread, I had WAAAYY too high TC's at first. This is with 8193 TC on 2 cards and 22400 on the 7950. Seems like the 2 x 270x's are underperforming just a bit (they were ~470 e, I'd be happy with 200-210 vert mining) Does anyone have recommendations for my setup? Here's my config file

My temp seems to be a bit lower mining this coin, is that normal? Only like 5 C difference.
