Yes.

<How much faster is the 68010?

Depends on your application. When I did mine, I ran some benchmarks,
and it came out to be about 5% faster. Other people claim as much as
25%. The latest version of the Lattice compiler has switches to
generate code for it as well as other compilers. Running benchmarks
on a 68010 with compiled for an '010 and comparing them to the same
benchmarks compiled for the 68000 might be interesting. I'm not going
to do it.

<Is it compatible with 68000?

Mostly. Some instructions are privileged on the '010 and later
processors, and some older software will trap on that. There are a
number of software fixes for this available, if you should have that
problem.

<And most off all is it worth the trouble?

Once again, it depends. I have a magic touch with hardware - I open it
and put my fingers in it, and it breaks. I didn't think the change was
worth it. If your applications get more improvement, or you're don't
have a hardware black thumb, it could well be worth it. The
cost/performance ratio of your amiga should go up in any case. Don't
forget what it may do to your warranty.

PS: I think this comes up often enough to warrant an entry in the
"answers to commonly asked questions" posting. Could this be made to
happen? And my apologies if it already has.
