Both of these laptops are about $500, but I'm not sure which graphics card is better; one site I looked at said the 7670M was faster while another said the 6620 is better. I'm assuming the true dedicated graphics card (7670M) is faster but one site said that the 6620 could play Battlefield and the 7670M cannot.
