Only FireGL cards support 10bit.
What apps support 10bit color?
Photoshop CS5(and others windows apps i think)+Windows 7+ATI FirePro Series +Wide wamut display = 10bit per channel colour.
I need to buy a new graphic card, so I want to know if can go to a "consumer" ati card if it can support 10 bit (Radeon HD 5000 Series) so I can use to games too, or go to the ATI FirePro and can't use for games (or I think so for the FirePro series). To the date it appears I must go to the 2nd option.
