I'd be pretty cautious about a multi-processor solution. In order for
it to work for you, you must be running more than one process (not the
case here) or the application software must be written to split the time
consuming work into multiple threads that can be simultaneously handled
by more than one processor.
While image processing is probably more amenable to splitting up the
work than some other computationally intensive tasks, the additional
programming work is not trivial and I would be skeptical that even PS
has expended the extra effort to implement it.
If PS does not support divvying up the heavy tasks then you would be a
very unhappy customer when you discovered that, not only was the second
processor not helping out, but was actually dragging the first processor
down a bit by the necessity of synchronizing inter-processor communication.
Just go with the fasted uni-processor you can find with the greatest
amount of physical memory you can stuff into it. Fast hard drives are
also good but nothing improves the performance of virtual memory faster
than more physical memory.
