Just got together a 3x Sapphire 7950 rig, mined only a small time, PSU is having issues. Just
ordered another one, will be back at it on Tuesday, I hope.

Out of the box it was getting 1800kH/s easily. Some tweaking will take it closer to 2000kH/s assuming
the new PSU works correctly this time. 

Cool! Thanks for the info.
