I've never had to change the nice-ness of any povray run. When the machine is 
just running povray it runs at 800% (or very close to it). When I do 
something else (like start FF) then that program will get some attention from 
some cores but those return to povray as soon as the new program is on 
screen.
I'm running Povray on AMD FX-8 (8 cores) with 16GB.
