How many documents did you open with word an excel? I've just checked - A freshly opened Word 2003, with no open documents, has a memory footprint of 25,336KB (24.74MB). Excel's footprint on memory was a measly 9,128KB (8.91MB). You're going to have to open a huge number of files in either program to even begin making a dent in your 8GB ram.
Simply opening the programs is not enough - make them actually do something.
And the one reason why you loaded 10GBs of photos into Paint Shop Pro, and you couldn't get past 3.5GB memory in use, is because you can only work on one image at a time, and the memory used by the other images is swapped out to the page file, in favor of the one being edited. You can work out how much memory a particular JPG file will take up in ram using this formula - ((X x Y) x 3) / 1024
- where X & Y are the dimensions of the image, and the 3 is each of the bytes for Red, Green and Blue color bits, and 1024 is the number of bytes in 1KB. A JPG image of 1600 x 1200 pixels will then take up 5625KB of memory, or 5.49MB. But it doesn't really matter, does it? Because the memory used by an inactive image is swapped to the page file anyway..
The one biggest factor here in your case is that PSP is a 32-Bit program, and despite the OS being 64-Bit and able to address the full 8GB of memory, 32-Bit programs are architecturally limited to a 2GB memory space allocation for both code and data. 64-Bit applications do not suffer from this limitation.
