I ran a core2 duo for years as a server, it was more efficient then any of the newer stuff I could find. I just upgrade to an I7, which costs more energy annual

  It's probably also more energy-proportional. newer CPUs and hardware in general do a much better job of scaling power use with demand. so if you're not running flat out 24x7, you're probably using less power in practice, even though your max may be higher now.

    Good point, it certainly seems to run cooler.
