I have been using a regular i7 based laptop + Dell 2711 running Ubuntu-64 as my primary photo editing till now and plan to build a new system with deep-colour/wide-Gamut support (10-bit/channel) work-flow. Since Dell-2711 supports 10-bits/channel (and also supports wide gamut AFAIK) I was wondering

- if there are stable drivers from AMD or OSS drivers that enable this (AFAIK this is not possible in consumer graphics cards but only on the FirePro and other workstation series) ? if yes has someone tired it ?
- if there are RAW processors/ Photo Editors that actually make use of the 10-bit work-flow (I use Corel ASP & GIMP which AFAIK do not support deep colour)
- if there are Spectrometers/Colorimeters that work on Linux (similar to the Hughski ColorHug) that also support 10-bit/Channel

would love to know your opinion before I plunk the money (around next week). Please do suggest alternate set-up/s if any (I'd like to stay true to Linux so changing OS is not an option)
