Going to be getting a Dell Vostro slim with these features. What should I change or is it good as I customized it?

Why would he need more ram, name 1 game that uses more than 2 gigs? Unless he is playing 2 games at once, and watching a movie, and playing music...

If you have read the Gamespot hardware performance guides. Not a single game had any change in performance when they increased the ram from 2 gigs to 3 gigs.
