Since I’m only photoshop user I’ll cover the photoshop issues only.
A good starting point is adobe photoshop site. http://kb2.adobe.com/cps/404/kb404439.html
You can browse the site for other similar articles.
The essence is
File size capability for Photoshop CS5 and CS4:
• PSD files: 2 GB
• TIFF files: 4 GB
This table lists the amount of RAM available to Photoshop with the different versions of Windows:
Photoshop Version Windows Version Maximum amount of RAM that Photoshop can use
32-bit 32-bit 1.7 GB
32-bit 64-bit 3.2 GB
64-bit 64-bit as much RAM as you can fit into your computer
And something that adobe doesn’t tell you. The windows 32bit application can address maxium 2GB address space. Adobe photoshop doesn’t use the windows default virtual memory manager. They implemented their own way to mange huge data via scratch file. This solution increase the overall performance while make system more fragile in case of wrong setup photoshop performance preferences e.g. crashes, error etc.
I think that you have nice system that must be responsive even with huge 20+Mpixel files.
If you want to unlash the power of your system you have to go to 64bit OS and use the 64bits version of photoshop CS5. Photoshop CS5 distributions includes both.
I don’t understand why you cannot upgrade your RAM. I assume that you have 4x1GBat you LGA775 mobo. I’d suggest you to replace the two DIMMs with 2x4GB. It will make your system 10GB – 2x1gb + 2x4gb
Success,
