I was responding to the heat question, not cpu load. Other than that, 
you're right of course. :)

Yes I have, and no there isn't.

That one I haven't tried, thanks for the suggestion!

I haven't, mostly because in the past some things I wanted were not 
available in amd64. I'm running a C2D in i386/SMP. Trying amd64 is a bit 
more of a jump, but when I get my HD repartitioned I can try 7.3 i386 
and -current amd64 ... back to the drawing board ...
