Asus Matrix HD 7970 Platinum Review @ OCC
 

From what ASUS has said about this card, the user is just about guaranteed to hit 1200MHz on the core or beyond. I've managed to hit the 1.3GHz line — faster than any other comparison video card. The larger PCB, 20-phase power design, and excellent cooling allow this card to really overclock well. I would love to see one of these on dry ice or LN2 and see how fast it can really go!
