Let us have another look at our Sandy Bridge chipset comparison table.  If you bounced straight into this page of the article and missed the blurb on the front page, I mentioned the two main differences between the P67 and the H67.  On H67, we can use the integrated graphics on the processor at the expense of CPU overclocking opportunities, and if we do use a discrete GPU, we are limited to one only.  Considering that a large portion of the pre-built PC sales worldwide feature no-overclocking and limited graphics, the H67 offerings, in micro-ATX form factors, offer a path into a highly contested market between PC builders.
