My computer operates with 2GM mem, 2 WD Raptor HD's and a Pentium 4 proc.
Can I expect a performance boost by increasing the mem to 4GB?
Software used: Office 2003 and Corel Draw, Photoshop and Painter.
Increasing memory often helps with Windows Vista, but it isn't some kind of
magical secret performance button that always works no matter what, or else
you'd see people with 800Mhz Pentium IIIs with 4Gb of ram administering
benchmark smackdowns to people with 3.8Ghz Pentium 4s and only 512mb of ram.
If you are short of memory, that is, if performance monitor shows a high
instance of stuff being paged to disk from ram and then back again then you
might see an improvement because adding more memory obviously helps if you
need more memory. If your performance problem is your graphics card being a
bit slow, or your processor being a bit slow or even the processor / memory
frequency being too low then adding more memory won't help.
The best route to good performance is to assemble a "well-balanced"
computer, to ensure all the components are good ones which allow all the
other components to work to their best potential (and it sounds like that is
what you're trying to do from your spec above, I'm not criticizing here!).
As John notes, you are using packages that tend to ask for a lot of memory,
but then you actually have a reasonable amount of memory. If you had a lower
amount of memory, e.g. 512Mb or 1Gb, I would certainly suggesting just
adding more, but in the position you describe I'd take the time to properly
investigate any performance issues you feel you have before rushing out to
buy anything.
