Remember that the 68030 has internal instruction and data caches (256 bytes
each?) so it can do quite a bit without even looking at the memory.  I don't
know what the system speed wil be, but speeding up the 68030 would still do
quite a bit for performance.  The TT also supports burst mode transfers for
filling that cache in the "TT-RAM" which isn't shared by the video and sound
subsystems so it'll be able to perform fairly well.

As I understand it (if I'm wrong, send me _MAIL_ and I'll correct myself),
the Amiga A3000 25MHz version still runs with a 16MHz memory system as well.

Have fun!
