I invariably recommend AMD64 these days (socket 939).

My off the shelf 2.2GHz system is on par with a 3.6GHz intel
equivalent (EMT64(?), ex-pen-sive!) for the interesting stuff.  System
is 2-3.5 times faster than Athlon at same clock.  Memory throughput is
a dream.

The timings given (by Granlund) are a true eye opener:

Today's intel 64bit cores are a lousy hack at best.

Alternative architectures (PPC) might be fine but are surely
much more expensive.
