Quote: Performance of the HD 6850 is targeted at just below the GTX 460 from NVIDIA with the 6870 being targeted just above this level of performance. To compete at a higher level of performance, NVIDIA has upped the ante with overclocked editions of their GTX 460. The Black Edition is an answer to this challenge. The HD 6850 Black Edition really ups the performance when you increase the clock speeds up and above the already large factory overclock.
