Building on the success of its TOXIC range of water cooled graphics solutions, SAPPHIRE Technology is set to launch its fastest graphics product yet - the new SAPPHIRE HD 2900 XT TOXIC. The SAPPHIRE HD 2900 XT TOXIC features the latest unified shader architecture with 320 shaders, the world's first 512-bit memory bus, native DX10 and Shader model 4.0 support. The new SAPPHIRE HD2900 XT TOXIC also features a drive-bay mounted water cooling system with integrated reservoir, pump and radiator system, efficient enough to cool not just the graphics card, but optionally a CrossFire pair of SAPPHIRE HD 2900 XT cards. SAPPHIRE is already shipping standard editions of its HD 2900 XT and is expected to ship the TOXIC version in the coming weeks.
