Have you ever actually _tried_ it?  I replaced the CPU in my XT with a V20
and realized very noticable increase in speed, running a variety of apps.
If the increase was only 5 - 10%, I really doubt that I would notice it.
I'd say, on the average, I got a 40 - 50% boost.  (Just for GP, it went
from 1.0 to 1.8, just like the original poster.)

I do agree with you that the SI is rather unrealistic, for the reasons you
cited.  I'm just offering my hands-ons, personal expirience.

Anyone else out there with V20's?

Brian
