Im getting a computer for my son, but i dont know which one ?

First one has better graphics card but less ram and slightly less processing power. It all depends on what he does. Is he the type of person who only has 2-3 programs open at a time or one of the people who have 15 internet tabs open, chat programs and games open. If only 2-3 programs at a time get first one. If he has the entire internet opened at same time get the second one.
