You might also take this opportunity to upgrade your firmware, if needed.

You don't even need to reconfigure, just pop the processor in and it'll 
work.  You could do a 'boot -r" just for the sake of completeness, but 
it's not necessary.

As far as dual vs single, Dual will *always* help speed up the user 
experience.  With a system like Suns, especially using Solaris, you 
will notice dramatic speed increases with a second processor.  Suns 
have amazing multi-proc ability.
