My memories are similar - probably never seen over 56 MHz mentioned.
Let's change those memories then :-)
68030@64Mhz. Behold:

http://www.amiga.org/gallery/index.php?n=3101In the AIBB tests the base system is an A3000@25Mhz. It's quite obviously eating dust! :-)
Also Doom (using latest ADoom, clean AOS3.1-40.42, no extras/patches/etc., KS3.0-39.106, no maprom stuff) feels better/smoother/more playable than on an A4000@25Mhz->31Mhz, but haven't really benched it. But on the A1200 rev.1D1 030@64Mhz w/ full SFX+music+MMU+FPS+AGA @ 320x200 NTSC LoRes+HUD showing, FORCEDEMO gave:
Blit wait time: 904us/frame (noMMU=995)
Safe wait time: 441us/frame (noMMU=485)
Chunky2Planar: 16396us/frame (noMMU=16479)
Note if you try to compare: clean OS vs. patched OS, SFX, music, screen size and showing FPS make a substantial difference in performance.
@Miked:
I guess to answer the original question: you can push the 030@40Mhz to 50Mhz with the right crystal, but as others said, the glue logic might not allow (my guess is it will since the CSA Derringer was 50Mhz capable - but on the Mega Midget Racer without RAM board+SRAM you can't go 50Mhz, that I've tried), but if it works, then make sure you add a fan to cool down the whole thing, especially in the cramped A500 case. I personally would put a small heatsink on the CPU/FPU and have a fan blowing sideways so as to cool more than just the CPU/FPU pair, because in the end those you can replace, but the soldered chips...?
Shameless plug: if you need crystal oscillators (or 68030@50Mhz/68882@50Mhz), I've got a number of them here:
