  The numbers I have seen for 486 performance indicate that it is
*about* 2x a 33MHz 386. Depending on which CPU intensive benchmarks you
run that figure can range from 1.5 .. 3.0. If you assume that the 33MHz
386 is linearly faster than the 25MHz version, then the value you get
is: 5.4 * (33/25) * 2 = 14.8.

  I have not measured these values personally, so all I can quote is
early published figures. These *seem* to indicate that the 14 is not
totally bogus, although I don't blame you for beling cautious.

  I'm waiting for the 50MHz 486 to be out before I upgrade again.
