Hi all. Am about to swap my cards to a single 7990 instead. The 280x can be undervolted to 1000 mVolt and underclocked to 940 Mhz core. 130W and 260-280 sols/s. The 280 can be undervolted to 1070 mVolt and is default at 940 core. Can be O/Cd to 1100 core and then produce around 310 sols/s. Otherwise its 260-280 sols/s.
the 280x is installed in the rig atm. If you want pics/more info, just ask
here is a pic of the rig running the 280X and a radeon 7990.

anyone interested? I accept cryptocoins in almost all forms
