It would be much more informative to hear from people who use Debian for things that require 3D acceleration -- Minecraft, running Windows games under Wine, Blender.

I have a laptop with nVidia Optimus, so I use Bumblebee. Ah, I see this is in the Debian repos [1] -- maybe I should give Debian a try!
