It's a fair bit faster and YMMV, of course, but 30-40% is not an
unreasonable expectation.  The core technology really has improved;
it's not just another 486 inside with deeper pipelines and a faster
clock.

Not enough to make it work the current cost delta.

I clock my P6/200 at 233Mhz and it seems to work just fine.  Many
others I know are doing the same without any ill effects.  Other kinds
of overclocking I simply don't know about.

The Tyan motherboard dual-P6 MB is quite nice.  I'm probably
going to get one for freefall just because you can stick a lot
more memory in the dual-processor model.
