  Since Nvidia doesn't make the cards (as far as I am aware), it's up to
the card manufacturer (Asus, Elsa, etc.) to give you the ability to use
stereo.  The fact sheet pdf of the Elsa Gloria III, which uses the
Quadro2
Pro GPU says that you can use stereo, but the card has no 3 pin port for
the familiar Stereographics type emitter.  I know there are other
systems, but will normal crystallographic software drive them under
linux?    That is why most people talk about ATI and 3Dlabs (oxygen,
wildcat), since they have the port.

  Both are probably over-kill for stereo X-lines graphics, which
is what electron-density fitting uses, but that is not based on any real
experience.  

Hope that helps,
