With the current threads about processor pickin's, this article might
be interesting to those.

Snippets from the conclusion:

"While the comparison of different Intel processor generations
revealed performance per watt improvements of over 400% if you compare
the a 3 GHz Pentium 4 630 and a 3 GHz Core 2 Duo E6850, AMD only
managed to improve its performance per watt ratio by less than 60%
(Phenom quad core compared to the Sempron single core). The
performance per watt results will be more impressive if you run
intensive workloads; thread-optimized applications will benefit even
more from multiple cores."

"If you want to go for an AMD processor, the Athlon X2 or Athlon 64 X2
still are the most reasonable choices. These processors are affordable
- some are even downright cheap - and they still deliver sufficient
performance. Enthusiasts with a demand for high performance under
threaded workloads should look instead for a Phenom (once the B3
stepping is available) or Intel's Core 2 processor family, which still
is the champion when it comes to performance, and often the leader in
performance per watt as well."
