Since xeons are limited to 550mhz max, if you want a 4-way box, and since DB is roughly 2,000 times faster, you would need a machine with about 2K cpus. But since that would not be SMP, and since current programs like DJ are not built around something like PVM for message-passing, it would probably take on the order of 4K=8K cpus to catch up, assuming the necessary programming changes were made (which is way non-trivial to do).
