The Amiga World regurgitation of the GVP claim that their 50MHz '030 board
is faster than the '040 has SOME merit...sorta.
 
If you're the type of person that looks at MHz as the end-all, be-all of
CPUs, then yes 50MHz is faster than 25MHz.
 
However, this theory doesn't hold much water when you consider the '030
uses both clocks, meaning it's actually running at 12.5MHz, as opposed to
the '040 which has a single clock, giving it a "real" 25MHz clock.
 
The 50MHz '030 might get close to the integer performance of the '040, but
no other CISC chip out there has its floating point performance
(3-3.5MFLOPS).  Floating point is where you'll see render times decrease by
an order of magnitude.
 
PS> I hope I got all the terminology right when I described the way the 
    clocks work on the '030 and '040.  I seem to remember it being
    described that way in a post from Dave Haynie, many moons ago.
