If you have those uber expensive toys, you need Windows 7 to play with them. Linux won't get you anywhere. Even if it opens 30 bit display mode, what ''APPLICATION'' can you use to utilize that? On Windows we have the legendary Photoshop CS4, that not only utilizes 30 bit color depth, but also uses GPU to do the actual processing.
On Linux, we only have gimp, what a piece of joke.
