LOLWUT? A CPU does not provide any PCIe lanes, that's the northbridge. Also, there is a negligible difference between x16/x16 x8/x8, as well as x4/x4. The P67 chipset provides a max of 16 PCIe lanes. That means any regular P67 board is limited a x16 or x8/x8. x16/x4 is a BONUS, NOT A CHEAPSKATE MOVE.
