We knew what to expect from the HD 7970 when coming into this review but I had no idea what kind of performance jump we would see with the XFX DD Black Edition Overclocked. With its core speed bumped up to an impressive 1000MHz we saw big jumps in performance in all of our benchmarks putting this single card up with or above the performance of two GTX 580’s in SLI in some benchmarks! Add that amazing performance to the fact this is one of the sexiest cards we have ever seen and its no wonder why this card is already hard time find while most of the reference cards are still in stock. The only downside to the card is its idle to mid power noise levels when compared to the stock cooler, but when you put it under load you don’t hear a loud ramp up in speed like the reference cooler. All in all we highly recommend this card if you are on the market for an HD 7970, its going to run you around $50 more than the stock card but you get your money’s worth in the all-aluminum cooler alone. The extra performance is just a bonus.
