I've just upgraded by setup with nVidia K5000 cards and Dell 10-bit Ultrasharps connected via DisplayPort 1.2. 10-bit color is working great in Photoshop and Premiere Pro.
However, testing reveals higher bit depth settings in Vegas still only gives you 8-bit display color. There is almost no information I can find on this - but I've seen a few posts claiming that it might be possible with BlackMagic card - but that would lose acceleration I believe. And can't find anyone that has objectively testing.
I'm using a ramp gradient file specially created for revealing 8-bit vs. 10-bit.
