A second advantage to you is that if you compared one two chip PC with using two PCs, is that all hard drive memory is local, where with two PCs one of the two PCs will have to get at hard drive files through a local area network. Sometime a LAN is better because a 100mhz LAN will out perform a hard drive, depending on the speed of the hard drive.

In reality, there are always 10-15 tasks in the PC competing for the cpu chip to complete its task. You can see this when you bring up the task manager and see all of the tasks listed. The formatter and output services just become two of these tasks and NT will allocate the cpu chips based upon priority and need. Elixir doesn't do anything to make this happen.

Because two tasks can run at the same time in this configuration, the PC should be built with more RAM than one with only one cpu chip. It is hard to judge how much, but a good production PC would normally have 128meg of RAM. I would think a two chip pc would need about 196 or 256 meg of RAM.
