... in the above link that I noted it shows at the bottom of the page two separate tables. The boards that are currently out which can support both PCI 3 and the 22nm CPU's and then a list of boards which can support the 22nm CPU's only...
So, for example, the following board with a P67 chipset...
http://www.asus.com/Motherboards/Intel_Socket_1155/P8P67_REV_31/
..will support the PCI 3 std and the 22nm CPU's, accoding to that list.
EDIT: To show the image from the top of the linked page to illustrate that Asus themselves are advertising a P67 board with full PCI 3 and 22nm CPU support...
Yip I see that but it does not show under the specification of that board or Cpu compatability heres hoping but knowing Asus they will make you buy a new board
the second board from the left P867 (REV 3.1)
