Yes it can replace a 750....in some cases...
The CPU may be able to get more done, but there is more to a VAX than just
the raw CPU speed.  Yes it may blow away a 750 if you are doing a lot of
number crunching with a small number of users. But I don't think that
the disk are other equipment is as fast. But I do know our new 6320 is 
faster than our old 780. At 40 or 50 users it (6320) is still faster
than 20 people on a 780...and the 6320 has 6Mips vs. 3Mips (780)
(here we are back to the MIPS stuff....but they are the same CPU)

As an example (Non DEC stuff)....I was looking at the new Sun SparcStations
and the new IBM RT/6000 stuff. The IBM had a faster CPU but it seemed
to be a MUCH slower machine in terms of the user interaction and graphics IO.
