P67 vs Z68 in price


I'd assume it is because of the aesthetics and design (the heatsinks seem much more solid on the expensive P67 MoBos from AsRock vs cheaper Z68 MoBos) and availability (Z68 MoBos are becoming extensively common among manufacturers ever since their release, thus increasing availability and lowering prices; with lower prices and more features, more people buy Z68 MoBos vs P67, and that may cause P67 MoBos to be produced less).
