I don't know if anyone is using one (look at the Info Sheet to see if
anyone has reported it), but whether or not it's really faster would
depend on a number of other factors such as how well the faster processor
interacts with the rest of the system and how fast the other subsystems
are.  A really fast processor is pretty useless if it's data-starved, and
I don't know if the Q700 has the bandwidth to fully supply a 50MHz
processor.  I'd just hope there was a big enough external cache involved
:-)

I seem to remember Daystar offering one at some point, but that was a
_long_ time ago.

Later.
