The Power3D2 gives Wintel games more power than you can handle with the mind-blowing performance of an arcade in your PC! Based on 3Dfx's second generation chipset - the Voodoo2 - the dramatic performance increase clearly makes the Power3D2 a leader in high-performance 3D gaming entertainment. The Power3D2 provides full-screen, high resolution, and full motion frame rate making this the 3D accelerator of choice for gaming enthusiasts.

The Power3D2 works with any 2D graphics controller, using a video pass through connector, to provide you the absolute in 3D performance. Designed to work in an industry standard PCI expansion slot, the Power3D2 is optimized for Microsoft's DirectX/Direct3D and 3Dfx's low level Glide interface.
