If you are happy with the performance you don't need more memory. One gig is
more than sufficient for the average and slightly above average user.

Now, if you are into video editing and heavy photo editing (using PhotoShop)
more memory "may" be an advantage.

I've never thought much f Sandra, and always thought it was a poor product.
Your message adds fuel to that point of view.

Highly unlikely. In fact my guess is that you already have considerably more
than you need.

How much RAM you need  is *not* a one-size-fits-all situation. You get good
performance if the amount of RAM you have keeps you from using the page
file, and that depends on what apps you run. Most people running a typical
range of business applications find that somewhere around 256-384MB works
well, others need 512MB. Almost anyone will see poor performance with less
than 256MB. Some people, particularly those doing things like editing large
photographic images, can see a performance boost by adding even more than
512MB--sometimes much more.

If you are currently using the page file significantly, more memory will
decrease or eliminate that usage, and improve your performance. If you are
not using the page file significantly, more memory will do nothing for you.
Go to http://billsway.com/notes%5Fpublic/winxp%5Ftweaks/ and download
WinXP-2K_Pagefile.zip and monitor your pagefile usage. That should give you
a good idea of whether more memory can help, and if so, how much more.

It may be reporting that you need more virtual memory.  The
computer needs enough reserved space on the hard drive to
page the contents of the RAM when you open new programs or
large files.
