Jane,

First, I have not used a dual mac, (though I have
used many multiprocessor unix systems) and have not
used OS X yet. I do program professionally, and
own a older G4 tower.

Executive summary: Yourn particulars probably
won't benefit too much from a dual processor.

From your description of your work, the only
thing that I think you would notice a significant
increase in a dual is the fact that you like to keep
several hungry programs running at one time.

If this means they are compute bound (I.E. you get
a progress indicator that makes you wait for an
operation to complete) then a dual cpu may be
of great benefit for you. But does this happen
in more than one program at the same time?

If hungry<\i> means that they are memory intensive,
the dual may not get you much improvement, since the
memory bus will be the limiting factor. In that
case you should keep your real memory up to your
needs.

Processor speed should not impact your web experience
significantly, even with a cable modem. You will
find that the web server you connect to may be the
limiting speed once you get broadband connections.

When you are on the dialup line, your modem is
almost always the limiting factor, unless you are
connected through a terrible ISP, or to a web server
that is underpowered/overloaded.

Cable/DSL are great, and I have frequently loaded
quicktime movie trailers at realtime speeds on my
cable modem (though that may degrade as more people
get on line with cable modems) When you upgrade you
will enjoy them. I also use my Cable modem with an
airport base station (though the base station can
be a bit tricky to config it will work.)

That being said the dual processor should have some
impact on you especially with OS X, since it has many
programs that run just for the OS, so they can easily
be split between the two processors.

The best benchmark is however your typicall
own usage, so if possible, try a dual out for size
at your local shop.
