The overclock on the core and memory helps the XFX HD7870 Black Edition to perform at an almost identical level to the more expensive HD7950.
those cards are pure sex. Id probably want the 7950 though if I was getting an XFX DD card. seems to make more sense, especially when overclocked to the limit.
Good cards, but far too many to choose from in the last 2 weeks. hard to know what to buy (if I was in the market).
HD6850 is the better value card IMO, its under £200 now in the UK, 6870 is too closely priced to 6950 IMO
