Actually the problem seems to be that you have assumed that we know
things you haven't talked about. You initially asked for hardware advice
without describing the problem you're trying to address. You asked for
the "Most Bang for the Buck", and in the general case that is definately
not SMP. Faster memory and more of it, as Chris mentioned earlier, is
usually the cheapest way to get some bang on a typical workstation.

This is the first time in this thread that you've mentioned what you're
trying to do with this hardware. You're still not providing anywhere
enough detail for us to give you a detailed response. What kind of math
are you doing? Does it involve manipulating large sets of data? Or
really big numbers? Are you working with integers or floats? Are you
dealing with matricies? What libraries are you using?

Profiling your existing system using vmstat, as Ralph suggested earlier
in the thread, and posting the results would provide at least something
to work with.

Explicit details about the kind of problems you're trying to solve will
get you relevant answers. Vague, newbie questions about "nifty" stuff,
such as an SMP box recently featured on Slashdot, will get you the kind
of answers you've recieved so far in this thread. Smartass comments
dirrected at people who are donating their often valuable time in an
honest attempt to help you out will get you ignored.

| When I can buy a single CPU that runs at 96 GHz, let me know.

When the performance of 96 1GHz CPUs in an SMP box approaches that of a
single 96 GHz CPU, let me know. I have to go with the ascerbic Mr. Park
when he says "If you have to ask about SMP then you don't need it". And
I'll go even further to say that you probably don't want it either since
it's more expensive, more complicated and more noisy.

If it's the case that you want SMP instead of needing it then that's
clearly something different. If so, you should make it clear that you're
looking for a cool toy to play with instead of a tool to solve a
particular problem.

Finally, you haven't said anything about budget, and none of this stuff
is free. Those nice Celestica boxes come in at about $15k but I'll warn
you, they're anything but quiet. :)
