    That would be nice, it increases the the value of purchasing such a card for linux. It makes it a bit easier to justify such a card for linux use.

    Yes, I am fairly certain that's supported.

    /me nods his head...

    Now, if only we could get that, get all the players to give us basic functionality on the cards in an open manner, we'd have quite a bit fixed in that space.

    Heh... I'm SURE that they'll get their act together...eventually. I'm a bit concerned about them claiming that the Workstation market's their main market for Linux and that they need to have closed drivers in that space- if that were honestly the case, you'd expect to see "better" results.

    Then, that's AWESOME. I'd figured that they'd thought along those lines, but not having had a chance to play with any G80 hardware, I didn't know if there was "issues" with that configuration or not.

    I guess if they're going to CUDA with PhysX, in addition to their dedicated hardware for it, I might be inclined to go looking for an SLI motherboard and Laptop, then...

    You can run a second NVIDIA GPU with CUDA in a secondary PCI-E slot not connected to a monitor (and not necessarily an SLI board) while the first monitor is connected to a screen.
