One important thing here: while R is not multithreaded, on Mac OS X,  
R uses a special BLAS which is multithreaded. So anything involving  
linear algebra (which for some problems is a major part of the  
computational load), will benefit from having multiple CPUs in the  
same machine. Depending on your problem this may be indeed speed up  
your things.
