Sapphire Atomic Watercooled HD3870x2
1Gb DDR3 

Witness the Evolution of Resolution with Attainable High Definition 1080p

A painted sniper perched, in the shadow of a distant oak tree, adjusts his scope to pick up the subtle differences between the two figures in his sight. With trusted precision the final judgement is released from the barrel and finds its home. Once upon a time such in game capabilities as sniper shots through brush were not possible, but with the advent of 1080p, DirectX 10.1 and Shader Model 4.1 technology’s, such headshots are quickly becoming commonplace, but require the hardware to push it. The era of playable true HD has arrived and with it comes a new era of precision gameplay and HD video playback via Blu-ray and HD DVD! The ATOMIC HD 3870x2 marks a turning point in the gaming industry as the raw power of two HD 3870 GPU’s combined onto one board, outfitted with a lofty 1GB of onboard memory and cooled by the industry’s most robust thermal water-cooling solution, unveil the evolution of how games are played!
