[gentoo-user] emerge --emptytree : how to ?

[Helmut Jarausch]

Hi,
I'm considering buying a new monitor (and graphics card) which supports
10 bits per color channel.
Will Gimp on a Linux machine (X11) support this now or in the near future.
Or is it just waste of money to buy a monitor with more than 8 bits/color 
channel?
Many thanks for some hints,
Helmut
