I have used a v20 for several years.  The only problem I have ever heard is
that with a PC >5 mhz you need to also replace the clock chip as well.
But this was only until the next version was available, (this was 2 years
ago and I an assuming it is now available).

As far as speed, it will run from 10-50% faster than before but this is
only for CPU intensive operations, remember that your disk is still the
slowest thing there is in the machine.  

The V20/30 gets its increase in speed by using the 80186/80286 addressing
technolegy into an 8086 package, this means that address resolution is done
by hardware, not a micro program.  At least thats what I remember about it.

GO FOR IT
