Well, if it works for you and you like it, then that's all that's necessary.
Sorry to sound a bit like a troll, but I'm just trying to say that crippling games just to get them to work or putting up with very slow frame rates isn't really worth it in my opinion. I just wouldn't like to see 68k people as disappointed with Quake2 as many were with Quake.
But as you say, if 060 is fast enough, there's no problem. I just haven't tried it. ;-)
