The following is from  <http://www.apple.com/powermac/> and would  
indicate that OS X, as well as some other apps (especially multi- 
threaded apps), do indeed benefit from having more processors/cores.  
I have no idea how much they do though, and assume that Apple's claim  
up of 'up to 69 percent faster performance' is the best they could  
achieve under ideal conditions and probably not what most average  
users might expect to achieve.

'Multiple Cores and Mac OS X
Mac OS X makes the most of multicore systems, since it was designed  
from day one for multiple processors. With symmetric multiprocessing  
and preemptive multitasking in Mac OS X, a Power Mac G5 Quad delivers  
groundbreaking performance.

Many of today’s applications are multithreaded, achieving up to 69  
percent faster performance on a Power Mac G5 Quad right out of the box.'
