It really depends,
I remember to have seen benchmarks (I think on XLR8yourmac) showing
that for certain games a dual CPU machine can be slower than same a
similarly clocked single processor one.
If the application is not multithreaded the second CPU is simply
useless. Even worse if you run OS9. The apps that really take advantage
of a second CPU are Phtoshop, Final Cut Pro, etc ... that are designed
for it.
www.XLR8yourmac.com is a good place to have a look at benchmarks.

Scott,
I think Bruce, Daevad, Pete, and Amanda are all correct. It would be
hard to make a comparison because of the type of app's being run.
I bought a Dual 450 Gigabit from another swapper a few years back. He
also had a Quicksilver 867 that I could have bought with about the
same RAM/HD setup. He also thought the 2 machines were about equal in
speed.
Maybe you can check some Xbench scores for a Dual 1 GHz G4 similar to
yours , then check some comparable scores for a single processor
machine and work backwards? Won't be perfect, but it might give you
some help. Probably will mirror the previous comments.
I recently upgraded to a Dual 1.3 GHz G4 (7455) and am very happy with
the results. Got a decent buy (GigaDesigns) from SmallDog.

Hey, G-Listers!
I have a hypothetical question for the collective genius out
there. Let's say you have a dual processor 1 ghz G4 computer, what
speed of a single processor in a comparable computer would it take to
exceed the dual processor performance? I'm guessing that it has
something to do with which programs your running. . .? Thanking you
for your input in advance.
