I know the built-in graphics has 1.7 gig graphical memory. But that's the total amount, before using some for display, etc. Does someone know how much is normally left? Is there a way to display it? I'm asking because when looking at the specs of some games nowadays, some require 1 gig, some 512 megs. I've tried a couple of the "1 gig" games and they may, or may not, work. (For these programs, ram or processor is not the problem). I'm sure others would like to know too, so thanks in advance.
