Another issue to consider when deciding between a DX and an SX is the cost
of a floating-point coprocessor.  When I bought my current motherboard,
I could afford an 80386DX only or an 80386SX/80387SX combination.  I wasn't
sure at the time that I would need the coprocessor, but I'm glad I chose it,
since I've made heavy use of it these past few months.  Even now, I would
not be able to afford an 80387DX (spare cash has been going for memory.)
