XFX HD 7970 3GB Black Edition Double Dissipation Review @ Hardware Canucks
 

The HD 7970 3GB is currently the highest performing graphics card on the market and AMD's board partners have been quick to take advantage of its willingness to overclock. XFX's Black Edition Double Dissipation not only incorporates higher core and memory frequencies along with a lifetime warranty but also uses a custom heatsink for a quiet -hopefully cooler- gaming experience.
