CrossFireXTM technology offers the most advantageous means available of combining multiple high performance Graphics Processing Units (GPU) in a single PC. Combining a range of different operating modes with intelligent software design and an innovative interconnect mechanism, CrossFireXTM enables the highest possible level of performance and image quality in any 3D application. Currently CrossFireXTM feature is supported with Windows® XP with Service Pack 2 / VistaTM / 7 OS. 3-way CrossFireXTM and Quad CrossFireXTM feature are supported with Windows® VistaTM / 7 OS only. Please check AMD website for AMD CrossFireXTM driver updates.
