This upgraded HD 6970 effectively replaces the high-end reference design in Sapphire's lineup, without the high-end markup. Sapphire's HD 6970 comes with 2GB GDDR5 memory, and even a little overclocking switch of sorts you can flick if you can unlock the card and get it all primed for tweaking. Hit our review to see how just how much we can push this top-end single GPU card.
