I have a few different 6950s currently up for sale.
3 Powercooler AX6950s (dual slot cooler)http://www.newegg.com/Product/Product.aspx?Item=N82E16814131393
Got 6950s mining right now. Can get you some pics if you'd like, but they may be rig pics since shutting down rigs to take out cards for pics - well, I might not do that atm.
Also, I have two reference 6950s that are shader unlocked to 1538, the 6970 shader count - an avg increase of ~30 or more mhash
Mhash wise, the 6950s are giving roughly 360-370 non ref and about 400+ ref, depending on how much you'd like to OC...these cards also can do Witcher 2 at 19x12, all ultra except ubersampling
asking 215 for the AX6950s (a piece) and 240 for the reference 6950 with unlocked shaders.
