Phenom 2 x3 720 is better value than the Intel dual cores at that price point.
I agree that its a great processor for the price but unless he gets the am3 board to go with it i think he is better off with the x2 version. the cheapest AM3 board is 140 bucks compared to 80 bucks or less for a good am2 + not to mention increase cost of ddr3 for said board.
