This depends on your application. Any generalization could be
significantly incorrect for a given application. Buying 32 nodes based
on some generalization could lead to significantly less performance per $
on your application.
If your power/cooling isn't free I'd also look at power usage, I've seen
power/cooling costs approach 50% of a 3 year cost to own for a $3k system.
In general a dual opteron has around twice the memory bandwidth and
lower power usage than the nocona. Additionally the new 90nm opterons
use even less power (per MHz).
