- Since you are not interested in the COP (for others... the 387/40 runs
- under $100 and the OverDrive(tm) runs much over $100, but the
- OverDrive is obviously much faster. You might be able to find a 487sx
- which would be cheaper than the OverDrive(tm))... the only advantage
- that I see is the local bus speed. If done correctly (0ws) you would
- have a much faster video and memory interface. Even if done
- incorrectly (1ws), you would have a system which was 5ns faster for
- each access.
-
- Choose the board with the fastest main memory access time... NOT clock
- speed.
