Hey guys, so ive been cruising around the forums for a while trying to find out what might be wrong and if I can fix my issue, i cant, so im hoping someone here can help me.

I have a decent set up yet im still not getting solid performance from my system in crossfire. In fact ive turned crossfire off and used only one card and gotten better results in some instances. Ill include as much system info as I have/know. Im hoping its just a stupid setting somewhere.

Cpu - i5 3570 (stock 3.4 ghz)
Mobo - AsRock z77 extreme 4
Ram - G.skill ripjawz 8gb kit (4 sticks at 4 gb each)
Graphics Cards - 2x Asus HD 7970's
PSU - Thermaltake Toughpower 775W

Catalyst suite 12.10 tried installing 12.11 beta and it just crashed my comp anymore settings you guys would like to know please just ask ill try to check as much as possible. This is starting to become very frustrating.
