Yes, I agree, and I use this also with my i7 machine. In addition, be 
aware of the following issue when rendering with radiosity on in a 
multi-core machine: the different threads are not released in order but 
when they finish their task. This results in isolated blocks being 
rendered within finished fields on the image. When stopping a render to 
start it again later, be sure to verify first that all finished rendered 
threads are consecutive, i.e. that there are *no* isolated unfinished 
threads in the image. When starting up render again (+C) rendering is 
started from the /last/ finished block; all isolated unfinished blocks 
are ignored and are shown as such in the image.

I hope I have made myself clear...
