More CPU's are not always a waste for a single threaded process - one
CPU to handle the OS, and one to handle your app is a prime example.

A lot of serialized processes can be pipelined through queue's and made
multi-threaded - I have one I am working on right now to transfer a few
hundred gigabytes from a legacy database to a purchased third party
product. It is serialized, but its very serialization suggests a
multithreading structure that quadruples its throughput on a single CPU
machine.

The 64 bit box with a SAN that I suggested is guaranteed to improve
performance, but it may not achieve the results he is looking for.

Without details, anything we say about Robert's process is just a guess.
