thanks for the update, which I'm cc-ing to the PsychToolbox discussion
group. I've added your report to the web page:
http://vision.nyu.edu/Tips/VideoCards.html#Radius
I can't help thinking that one or another of the video card manufacturers
might release a 10-bit version if they realized that the demand is there.
So it's worth writing to manufacturers to tell them that you want to buy
a card with 10-bit DACs. I suspect that very minor changes in the layout
of the printed circuit board would create a card that could be stuffed
with 8 or 10 bit DACs.
My guess for a company that's likely to be interested is Villagetronic
(http://www.villagetronic.com/e_feedback.html).
