RE: WTB: 560 133mhz 1gm Active Matrix, 8mb
Are these machines upgradable? I.e. if the performance SUCKS can I later replace the processor?

As I said, "given all else being equal".
For one thing, Robert, isn't your 133 MHz Pentium machine a Toshiba
Tecra? And your 90 MHz 760CD--that doesn't even use a PCI bus (later 760's
do though, right?), as I understand it! Indeed, there is likely to be a
plethora of differences between these two machines.
But for the 560's come in only 3 total flavors, the top to being
virtually identical in everything but processor & HD size. As far as I
know, there's not difference in design, architecture, etc. The specs I read
from IBM show they are essentially the same machine. Just one uses a P120
and the other a P133.

Given the above (same model, same series, same architecture, etc), I
think I can, though benchmarking would be preferable. But since nobody can
find a P133 560, that's not going to happen any time soon.
