Nowadays I think a single processor, quad core is likely to be cheapest
per nominal aggregate cycle, although there is also a quad processor,
dual core by somebody -- Supermicro?  that looks interesting and might
be a hair cheaper.  But of course what processor/core combination is
best for you likely depends on how solidly you're CPU vs memory bound.

Hmmm, not a lot of headroom there.  Better not get a CX1, even as a
gift...;-)
