	I think that a discussion of chip technology is wholly
relevant to this newsgroup, as long as Motorola 680x0 chips are a
main part of the discussion. I shouldn't use the term war, I
consider this to be a "discussion".

	I don't have MFLOPS statistics myself, so I'll take your
for truth. You mention a Weitek math coprocessor, which is not
made by Intel. That is something separate which is an additional
cost beyond the 486. Also, MFLOPS stands for "millions of
floating point operations per second". That is very important for
some programs (such as ray-tracers), but less relevant for other
programs, such as DTP. That's why benchmarks stink. For a DTP
application, MIPS is more important, although I'd prefer to hear
some Dhrystones and SpecMarks numbers as well.
