Charles, This is a cost/performance decision you have to make. A 68020 board
without a FPU and 32 bit RAM will give a varaiable performance
boost. From 1.3x to about 1.8x. The 16 Mhz 68000 will be just fractionally
slower. However, the problems you described are best solved with more
horsepower. If you spend several hundred dollars (I have no idea what the 14
Mhz 68000 costs) and find the performance unacceptable then the money is wasted
as it cannot be speeded up any faster. A bare bones '020 can be expanded to a
level that may be satisfactory to you. Again, this is a choice you have to
make. A simple enhancement is to replace the stock 68000 in your Amiga with a
68010 which costs from $15 to $35. It offers a 4 % improvement, but on some
programs that can be felt. I have one in my home A2000 and I can tell a
difference in screen updates speed in microemacs. The work machine is slugish
compared to my home A2000.
