How could there ever be such a thing as too much CPU power?  Too much
power consumption?  Sure.  But to much CPU power?  How could that
possibly be.

Even heavy weight media tasks have CPU stalls because of cache misses.
In theory, well written software would use hyper threading to take
advantage of running something else non-intrusively during the stall
time.  Reality may not work out this way though.

That may very well be.
