Hi, I have this mobo
And my question is - can I run 3-way GTX 670 SLI on this MB ? It has 2x x16/x16 and 1x x16/x4

More about : sli mobo

those gpu's are PCI-E 3.0 based so find a mobo with pci-e 3.0 slots.

I read there's no big difference, only around 5% ... And PCIE 3.0 cards are also compatible on PCIE 2.0 situated mobos

I dont think 3 way will work. The p67 only has 16 pipelines. If you run sli it splits them to 8x and 8x. If you run 3 cards you get 8x 4x and 4x. The GTX670 will easily saturate a 4x connection, it may even saturate a 8x. Chances are if you run 2 670s on that board it will be slower than just running one. 3 will defenitly run slower if it even works.

check out this note, its the bottom line in the specs from the asus site you linked.

*1: The PCIe x16_3 slot shares bandwith with the PCIe x1_1 slot, PCIe x1_2 slot, ESATA3G & PESATA3G and USB3_34. The PCIe x16_3 runs at x1 mode by default for system resource optimization. (PCIe x1_2 will be disabled.)

I have a feeling a video card wont even work in the 3rd slot.

doing 3 way sli of pci-e 3.0 cards into pci-e 2.0 will drop the performance about 10-15% because lack of bandwidth.
