How have you tested? My 5770 outputs 10-bit RGB via HDMI and the GTX460, 12-bit, according to my display (reported as 30 and 36-bit), but I have no way to tell if there's a practical advantage at all, or if madVR can take advantage of it. I'm thinking I'm gonna test madVR's 10-bit output, and if it gives me more banding than 8-bit (due to less dither, 1/4 if I understood what madshi said above and I'm not mistaken), then I guess it's not real 10-bit.
