The 486 is still faster than a 386+387.  This is because many of the
support functions are onboard the 486 CPU (like the 8k 
cache) but are spread over one or more extra chips on a 386.  This
does make a significant difference in speed.  In addition, you can
add a numeric processor to a 486 system to get even better speed.
