Didn't expect a response to my lame post, so big thanks.
Interesting. I do know that 10-bit cards and screens are available as I have been looking at them because of my photography hobby. In all honesty I stopped looking further when I found out OSX doesn't support it. There might be a workaround; I haven't dug any further due to the high costs involved.
I did see that Windows supports 10-bit. Would you know if Linux does as well? Just curious.
I like responding to posts that reference cool hardware, even if they are sarcastic. I'm not aware of any stable drivers for it on Linux, although a lot of VFX work is done on Linux. Some of the animation and compositing packages are certified under Fedora. It's favored for the ability to make performance tweaks more than anything. I have read that a couple Nvidia cards supported 10 bit paths on OSX briefly and unofficially under Leopard, but I can't confirm it. Even then you wouldn't have a full path without the software developers on board. It couldn't go Nuke --> framebuffer ---> screen 10->10->10. Windows supports it with specific card features enabled, so it is a rather small matrix of working setups.
