SMP operation and larger caches appear to be threshold features in 
Xeons.  Old Pentium III could be used in duals, but Intel's marketing 
has changed.  Normal Pentium4 is *not* dual processor enabled:

If you really want a fast dual CPU machine from Intel, you'll probably 
have to pay for a Xeon...

Sincerely,
Josip
