XFX Radeon HD 6870 Black Edition

In testing, the 6870 Black Edition routinely beat out the stock flavor with its factory overclock which is great, but expected. What is not expected, however, is the ability for this card to clock all the way above OCC's Core Clock speed comparisons with stability and not even need a voltage tweak. Overclocking this card was a complete blast, and being able to do all the things I can do with my 5870 at the same speeds while using less power, at a lower temperature, and with much lower noise levels while at those speeds visualized the concept of total refinement for me. Label me impressed.
