I wasn't sure where to post this, but will offer it as help for those who are a little less familiar with Photoshop. I have noticed a number of posts concerning the amount of RAM required and questions as to what might be needed. Actually, Photoshop has a neat tool that addresses this issue. To see how your memory is working, First, open fairly large file in PS. Now go to the bottom of the box containing the image and click on the right facing arrow. In the drop down box, click on efficiency. You will then see: Efficiency xx % in the box. Begin adding layers, masks, whatever to "work" the file.
As long as the efficiency remains above 90%, you are ok. If it drops below 70% with any regularity, this means that PS is requiring too much virtual (swap) memory. Means you need more RAM.
To find out how to easily allocate more memory (up to 75%), and to set up scratch discs for your best personal setting, Go to Adobe Technotes and click on "Optimize Performance of Photoshop for windows"
Hope this helps.
