I'm ready to switch out the 68LC040 33mhz chip in my Mystic CC mobo for a 68040. There seem to be a few 25mhz chips on ebay but I can't find a 33mhz or 40mhz for a decent price.

Compared to the FPU-less 68LC040, would there be much of a noticeable performance or speed difference between the 25hz and the 33mhz 68040 versions?
