My 5 x Club 3d 7950 cards went from around 2580 to 2620, over 520 pr. card, so i can't complain

They are getting hot in this summerweather though, like mining scrypt.
The problem i had earlier with my 5 x 280x elpida rig, seems to be gone after i have used low intensity (-li) settings. The 16 gig memory error is gone and the rig is running stable at last

There is no significant speed increase/decrease on the 280x's.
