the Boxx guys reccommended the nVidia Quadro FX 1400 or 3450. they are in 2 different price ranges.
the tech guy here at R&H reccommended the Quadro FX 1500 or 3500, but he did say the entire range from 1300 to 1500 is more than adequate for home stuff. if you need to do 2k playback, maybe step up to 3450 to 5500.
these are the only 2 places i've checked, and they are solid enough reccommendations for me.
but, just for giggles, before i actually buy i'll check the reviews in 3d world and see what they say, although the cards that don't come out until next month obviously won't be in there.
hope this helps! let us know what you get and how it works!
