I assume you mean a WarpEngine 040? If so, it's a great accellerator. Compared to the original Commodore A3640 it's much much faster because of the fast memory on the card. But, the 040 on it is simply a normal 040. So, another card (ie. Cyberstorm 040, T-Rex 040, etc.) with the same processor would have similar results.
As far as the QuikPak 060, that will run circles around the 040. IIRC it is the only accellerator that supports (ie. actually uses) EDO ram so it's memory speeds are very fast. Add the fact that the 060 processor is much faster than the 040 anyway.
