I have the ases P8H67-V motherboard with a 3 x PCI expansion slot and i want to buy the msi gtx 670 graphic card with the PCI Express 3.0. Would it be compatible ?

You have 1 x PCIe 2.0 x16 which it will work in.

Specifications>Expansion Slots
1 x PCIe 2.0 x16 (blue)
1 x PCIe 2.0 x16 (x4 mode, black) *1
2 x PCIe 2.0 x1
3 x PCI

it says the motherboard have 3 x PCI

so what dues it mean ?

3x PCI means it has 3 PCI bus slots
more info here http://en.wikipedia.org/wiki/Conventional_PCI

PCIe (express) is different and is in no way compatible with PCI.
the x16/x4/x1 refers to the amount of lanes the slot has (and max throughput)
the PCIe 3.0 refers to the revision of the PCIe slot. A PCIe 3 video card will work in a PCIe 2 slot.

Ok that made feel stupid.

one last thing, what the deference between the PCIe 2.0 x16 (x4 mode, black) *1 and the 1 x PCIe 2.0 x16 (blue) and the normal PCIe 2.0 ?

PCIe 2.0 is the same throughout. There is no "normal PCIe 2.0". The "2.0" simply refers to the standards version which the slot was designed to conform with (primarily data throughput).

PCIe 2.0 x16 (Blue) means the long blue slot on your motherboard runs at the full throughput of the slot's configuration. Think of it as a sixteen lane highway.

PCIe 2.0 x16 (x4 mode, black) means the long black slot on your motherboard only runs at 1/4 the throughput of the slot's configuration. Think of it as a sixteen lane highway with twelve lanes closed for construction.
