Has anyone used this chip with 386/ix?  From the manual, "Cyrix
CX-83D87 is a CMOS VLSI integrated circuit that is pin compatible
and software compatible with the 80387, yet ... achieves 4 to 10
times greater performance ... by implementing floating point primitives
operation in hardware."  
Given one floating point intensive process (a ray trace) I am 
wondering what performance difference I would see?
