Sapphire HD 3870 X2 Atomic Edition comes with pre-filled, pre-sealed and maintenance free watercooling. This allows Sapphire to ship the card with higher clocks, making the card the fastest HD 3870 X2 on the market today. As you would expect from such a premium product the presentation is outstanding, and so is the price.
