Yo FLOP's guru,

I owned a 386-25 computer w/ option that I can either install an async 387-20
or 387-25 sync. math coprocessor.  My question is :) does the 387-25 sync offers
a good bang for my bucks?  I heard that a 387-25 sync can offer about 
0.6 to 1 MFLOPs, how about 387-20 async?  
   
  (oddity: Crosstalk IV 's timing sped up 3 time if I set the motherboard ready
   for a 387-25 -> 25 Mhz sync operations.  Redemity/suggestion/guess??)


Thanks in advance for using the most powerful multi-everything computer
to process this msg.  :)))))))
