Hi, i am having to purchase a new pc as mine has bust, i was going to order a AMD A6 6400k 3.9ghz with mobo from a shop but a friend of a friend is selling a Intel quad core 2.40ghz i haven't a clue what model number for the Intel is but he says its like a i3? so my question is which is better? I will be doing light gaming and a lot of video editing and surfing the web. T.I.A
