2 x 4/275 vs. 1 x 5/300 CPU Comparison

Hi,

I'm looking at upgrading our 2100A with 1 x 4/275 to one
of two options:

        2 x 4/275
or
        1 x 5/300

And I was wondering if anyone had experience with something
similar, and how they found the performance increase one
way vs. the other.

Is it better to go a newer chip, or multiple older ones?

I'm running DU 3.2D-2 (soon to be 3.2G), and am using AdvFS,
so I know I won't get AdvFS multithreading from multiple CPU's,
however, 4.0 is scheduled for early next year, so I am not
taking that into account at this stage.

TIA,
Gunther
