I'm not going to make this conclusion any longer then needed, the Radeon HD 7970 is impressive at many fronts however we never expected the overclocking potential to be this good. It results in even faster performance while the surrounding conditions like TDP, heat and noise remain absolutely under control. That's free extra performance, at very little extra risk or annoyances.
O/C looks good
, i think we should see a sapphier vaporx style with a pretty insane o/c added
