yes, although you could simply increase the pageing file until you get mroe physical ram.
"right click my computer > properties > advanced system settings > settings tab under performance > advanced".
There will be a button called "change". Select "custom size" and make both box's "5000".
Paging file is a space on the HDD that is used as ram, it is much slower so physical ram is better, but this will speed your computer up as a whole.
