Just as an aside, the power savings going from two single-core CPUs  
to one dual-core can be rather impressive.  At work I run a computing  
cluster on AMD64 hardware, and we've been studying replacing our 2- 
socket single-core compute nodes with half as many 2-socket dual-core  
systems, and doing some similar consolidation of our support  
servers.  Part of the motivation for this is we've exceeded our  
available A/C capacity.  I ran the numbers and at the same clock  
speed (2.8 GHz) we could cut our power consumption (and, by  
extension, our heat generation) by a third.  By giving up 200 MHz per  
chip to switch to HE-series CPUs we could cut it by almost half.
