On paper, the performance numbers will look real good with the 4
processor..but I doubt any users will even see the difference between
the two.  The only reason I would buy the 4 proc versus the 2 proc is if
I have a ton of money to spend.  Unless, it the server will be very
dense (in terms of users) I would make sure the other components away
from the CPU is the best/fastest and stick with a dual processor.

Thanks for the input Al.  

Let me ask for more focussed feedback.  

Ignore the disk issue.  I'm not asking about that. 
I'm talking about Mailbox/PF server functions on one
box.  
FE functions are handled separately.  

By strictly comparing, 4 proc vs. 2 proc (and whatever
Bus stuff might come with that or other things that
I'm not familiar with).  Why should I spend 4 times as
much for a 4 way box over a 2 way box?
