[ I think Encore and Convex would argue that point ]

One of the points against multi-processor computers vs uni-processor,
given that both have the same total power, is that some programs just
don't allow more than one processor to be used. In those cases the
uni-processor, with a faster processor, will run much faster, assuming
that there is CPU available. This applies only to machines where there
is available CPU.
