- The memory bottleneck happens with any CPU board that doesn't have
- on board RAM. That is why all good accelerator cards have memory sockets. It
- doesn't matter which Amiga model you have (A3000, A4000), unless the
- accelerator you install has local fast RAM, your performance will not be as
- good as it could be.

-
- Even though memory access is a bit slower then before, you will still be
- faster than any 030 system. If the A3640 had on board RAM it would be faster
- than it currently is. I think that an A3640 card at a good price is still
- worth installing in a system.
