And when doing benchmarks, don't forget the speed advantage (or disadvantage) of the RAM bus speed. It makes all the difference in the world. Even between 68030 boards, faster memory access makes for a much more responsive machine. Of course the most obvious historic example was when people switched from C='s A3640 board with the slow as molasses m/b memory to a WarpEngine040 with direct processor/memory access on-board the cpu card. This difference is not so noticeable between different brands of 68060 cards. Phase 5's were generally the slowest with respect to fast ram speed/timing (which is/was good for overclocking), but they also had built in logic to speed up the cpu card to chip ram access speed (mimicking as closely as possible 68030 cycles, iirc) so it was a wash overall no matter which card you chose to buy.
