Why would you suggest that? Even a 1 GHz proc will be faster with a 9600 over a 4200. Not at 640x480 of course, but do you really think he cares about that?
If he gets the good card now, he can re-use it if he decides to upgrade his proc/mobo.
Some day I'll be rich and famous for inventing a device that allows you to stab people in the face over the internet.
