Uhm... stick with commodity CPUs?
Seriously, unless you're going to run on some seriously big hardware
you'll be hard-pressed to find better performance/dollar than going with
a server running Opterons.
If you're trying to decide how much hardware you need to meet a specific
performance target there's a company here in Austin I can put you in
touch with; if I'm not mistaken on the cost of pSeries hardware their
fee would be well worth it to make sure you don't end up with too much
(or worse, too little) hardware for your load.

Great. More performance data is always good to have.
