- I think it is about 10-15% extra speed. So yes, a 60ns SIMM would show
- some speed improvement but if you already have 70ns SIMMs it probably
- isn't worth it to get others.

- Hard to say, but it probably isn't sufficient so you might consider getting

- Some of the '030 optimized programs require and FPU and some don't.
- The programs that come in a version that requires an FPU are usually the ones
- that needs the extra speed most.
- Remember that you can always add an FPU at a later date if you find that
- you need it.

- The Blizzard cards are very good. Some of the other accelerators are also
- good but I don't know enough about them to be able to give an informed opinion.
- A Blizzard card might not be the best buy , but you can be certain that it
- won't be a bad buy.
