The major benefits from the Nvidia driver for me are working power 
management and working vdpau, which lets me play 1080P video smoothly on 
an old Intel core2 cpu. With the nouveau driver, my video card runs 
about 30 degrees hotter, and HD video looks like crap.  Of course, 3D 
rendering is much much faster with the Nvidia driver, but I don't play 
games.
