What about the CPU performance?

As I say it more likely shuts off all the functions and just uses the
50MHz CPU and the 16MHz FPU, hence the drop in FPU performance.
A 50mhz cpu and a 16 mhz fpu can run together?

Yes, when one is on an accelerator card.

Speedometer turns up virtually the same number for both on and off
PowerMath settings. Either it doesn't make any difference or it is not
supported on my card.

The two are functionally identical.
Watch when your extentions load, after
the Power Central CP loads the rest should load
