I currently am running an AMD FX62 dual core that I just put together about
2 weeks ago. At the moment, I have Vista RC1 using eudora email, powerdesk,
powerpoint, snagit screen capture software, IE7 with 6 tabs open to
different internet sites, and task manager. Also running is MS virtual PC
running XP using Photoshop and Acrobat with both physical and virtual
machines on my home network. Task manager reports all of between 1% and 3%
CPU usage as I type this. If I switch to the email program, the CPU usages
jumps up to all of 8% and then returns within a second. When the email is
checked, it jumps up again to all of 8% and then returns. Memory usage,
however, is at 1.25 GB. ...doing stuff like this, the machine is a bit
faster/quick-to-respond than my old P3, but if that's all I was doing, I
don't think that I would have bothered upgrading, since the P3's CPU usage
for such tasks was still down below 50%, and when it was that high, it
rapidly returned after completing just about anything those types of
programs might do. Where the machine is much faster is with software that
runs the processor for minutes or hours (or days). My video editing software
can now give me real-time previews and about 1/2 time renders and file type
conversions - e.g., instead of waiting for an hour, I can have the same
video clip converted in about 5 minutes. Where the old machine failed with
things other than video editing was with the RAM being maxed out (without
replacing smaller sized sticks with others) at 512 megs. This required
writing to the hard drive's pagefile, which is much slower than writing to
ram.
In sum, what you're doing is completely non-processor intensive (as another
already mentioned). You might be using a bit of ram (but much less than I am
right now), so additional ram might speed things up just slightly when you
are opening and closing programs. All else equal, a single-core processor
will run most types of software (but not all types), faster given equal
processor costs - e.g., you will get more speed from the use of a single
piece of software from a $300 single core processor than from a $300 dual
core processor. As others mentioned, dual core will only be worth while if
you are running cpu intensive software in the background that take much time
to perform a task while also wishing to run additional software at the same
time. Also, most software is not really written to make the full use of a
dual core cpu at this time.
Open task manager on your OS and carefully examine what is going on in your
current machine to get some idea about what given upgrades might provide. If
your processor is maxed out, then a processor upgrade will help. If ram is
maxed, then a ram upgrade is in order. If neither, you're not going to
accomplish a great deal other than a small bit of responsiveness switching
windows or starting up the software. If I had a 3000+ AMD with adequate ram
on my old machine and only ran email, word, and firefox, I might have put
money into a new dual monitor setup and accompanying dual dvi video card to
run it so that I could look at all of those windows at the same time, but I
wouldn't have put money into a new processor.
