Just want to throw a big thank you out here to all of the people talking about the new AMD drivers and new SGminer version out, in particular utahjohn. I've upgraded my linux rigs to the 14.6 drivers, updated my sgminer, tweaked my settings and overlocking and it's increased my hash rate on x11 by almost 50% over what I was getting before. Seriously... HUGE difference. Thanks a ton!!
