I'd put some more effort into evaluating alternatives.  A lot depends on how
much money you want to spend.  You can probably do wonders with your MV-II
by doing the MV-III upgrade and switching to a higher performance disk
subsystem.

The relation between your grahpics devices and the system isn't very clear,
but if you need a "powerful" supporting host, you may want to look at the
3800 type systems or the 3520/40 (ignore the graphics, count VUPS).  Some
of these things get pretty expensive, however a lot of the difference is
from perhipherals/memory/VMS licenses bundled with the configuration rather
than CPU price.
