NVIDIA today began shipping its long promised Fermi-based Quadro workstation graphics cards. They share the same, DirectX 11-capable (and OpenGL 4.1) cores as the GeForce 400 series and are theoretically up to five times faster than the models they replace. At the top, the Quadro 6000 has a large 6GB of GDDR5 video memory and can handle as many as 1.3 billion triangles per second across its 448 processing cores.
