: Cut in CPU power?  From My understanding... a 486 is a 386 with an onboard
: 387 and cache.  A 486sx is a 486 that has the 387 disabled, leaving you
: with what is basically a 386 with a cache.
: Now, this means he's comparing a 386 40Mhz with a 386 25Mhz with a cache.
: I leave the decision as to which is better up to y'all...


Thats not right is it?

The 486 has different timings (via clock cycles) and there for runs faster
(not by much) than a 386. Also there are some newer functions on the 486
(albeit partially useless ones). However i would stay away from an SX,
because if you want the co-pro. part, Don't you have to buy a chip which
is in fact a '486 which disable your SX chip?
