I was reading the online manual for my new motherboard, Asus Max V Extreme, and there's a section regarding the pcie 3.0 slot which my GTX690 needs. The manual actually states that intel 3rd gen cpu's 'support' the pci express 3.0. I am still planning on using my i7 2600K (I bought this 2 yrs ago) since it's still a good gaming cpu which I can overclock easily with this motherboard, but, will I not be able to get the full funcionality of my graphics card because of my cpu using this mobo?
