I know several Atari users are running 060's overclocked to 100Mhz in their Falcon but they seem to have
very big fans installed. I haven't heard of anyone going over 80mhz in an Amiga.
If you remove the crystal and place a socket there you can experiment with different speed crystals to find which speed works best and most stable. Let it run 68k quake for an hour or so to test.
On the
AIBB benchmarks page, an 060/50Mhz gets 26.74 Dhrystones, and 060/64Mhz gets 36.26, which is in line with the clock speed increase.
