In another press release from NAB, Nvidia has announced that the previously discussed QuadroFX4800 will now be made available to Mac users as an addon.  It won’t be cheap ($1800), but will support the 3-pin 3D Stereo connector and two dual-link DVI connectors.

NVIDIA Quadro FX 4800 GPU for Mac has a MSRP of $1,799 USD, and will be available starting May 2009 through Apple.com and select Apple resellers and workstation integrators. The Quadro FX 4800 for Mac will also be available through NVIDIA channel partners PNY Technologies (US and EMEA), Leadteck (APAC) and Elsa (Japan).
