You need to get the personal grid edition to make use of all the cores.

I had the same problem with my 4 core G5 Mac Pro (since retired).

I believe that Mathematica uses one core for the front end and one for  
the kernel by default. On a two core system, or even a 4 course  
system, that is usually sufficient, since one usually has other  
processes running. However, with an 8 core system, you should look  
into the personal grid edition to maximize throughput.
