Speed comparisons A500 etc.

Really this depends on the game.  Although I think you're going to get your "biggest bang for the buck" just by adding some fast memory.  Commodore was stupid to not include it in systems like the A1200 and CD32.  

Obviously adding a fast 68030 is going to make a big difference for games that use any sort of 3D, and with Workbench, if you plan on using 3.9, or any sort of high resolution, high color screen.

Or soon by adding a Phoenix accelerator.

Nice numbers, definitely.    Isn't that still just a fast 68000 core, though?  I know I'm just being picky but I'll hold off until they include >68020 or 68040 or FPU/MMU-type instructions, etc.

But for someone with no accelerator at all - awesome.

Good point about the 68010 above.  I've run them in all my systems.  5-10% boost, as Tenacious said (which was noticeable in Dragon Strike, plus a few other games), and you can buy them all day long on ebay for under $10 shipped.  I've considered combining the overclock mod with the 68010, but after reading the instructions (and all the warnings about it messing with floppy timing, etc.), it just doesn't seem worth the effort.

Is the A570 really not compatible with any other accelerator?  That sucks.
