CONTENT: Being the fastest single core graphics card on the planet, the HD7970 is going to be hard to improve. Considering that the reference cooler already performs very well and the stock AMD card overclocks freely, XFX certainly have their work cut out.

CONTENT: Enter the XFX Black Edition. With an improved over-stock clockspeed of 1120MHz on the core (120MHz faster than reference HD7770) and a huge boost on the memory clockspeed to 1300MHz (5200MHz effective), the Black Edition S (Super Overclock) arrives pre-overclocked which should give the card a fair boost in performance.
