Roughly this time last month we were testing a variety of graphics cards in the new Call of Duty: Black Ops video game. I remember picking up a Radeon HD 4870 and thinking to myself "wow I've had this thing forever," and in a sense I have considering this series was launched over two years ago. The follow up to this card was the Radeon HD 5870, a solid successful product for AMD as it remained their flagship single-GPU card for roughly 15 months, and it is only being replaced today. After a short delay, AMD brings us their new flagship GPU in the form of the Radeon HD 6970. Code-named Cayman XT this new graphics processor features 2640 million transistors, 23% more than that of the Radeon HD 5870.
