I can confirm 3275 on vapor-x, any good configs for 7950, 7970 and 290x?
I got about 2500-2575 on my XFX 7950s, and 1500 on my 270 when I tested them yesterday. I can post my settings later if there is any interest.
the xmod at I 17 is stable at 2.8-2.9 on my 7950 running 1075 core and 1300 memory its 70*C with fans at 59%

nice and breezy!
