Save the money from the dual itanium or quad xeon and buy a dual xeon
but faster disks with a larger cache in the RAID controller, and
perhaps a dedicated RAID controller for the disk set that holds the

You're sure to find that you saturate the disk system faster than you
fill up even one CPU, let alone 4.

I assume that the box will be running *only* the database and any
other applications will run elsewhere.
