HIS HD 7970 IceQ X² & HD 7950 IceQ X² Review @ Hardware Canucks
 

HIS's IceQ X² heatsink design is billed as one of the best around and it has now been paired up with AMD's HD 7970 GHz Edition and HD 7950 Boost. They've done this without adding a huge premium onto these cards which results in an excellent price / performance ratio, particularly when overclocking is involved.
