Little bit confuse..my 1st question is.. will all 22nm cpu support pci e 3.0? The second question is will h61 mobo like gigabyte ga-h61m-s2p support hd7770 (pci e 3.0 16x) graphic card, the manual book said it was designed for pci e gen 3. But the problem is they labeled 'Pci express 2.0' on it compare to other boards which is 'Pci express 3.0', that what make me so confused. In the manual also stated that in order to support pci e 3.0 i must install 22nm cpu. http://www.manualowl.com/m/Gigabyte/GA-H61M-S2P/Manual/240036

Is this mobo only for pci e 2.0 or it also can support 3.0 depend on what cpu i use? FYI i already have gigabyte ga-h61m-s2p with intel i3 3220 on it and planning to buy sapphire radeon hd 7770.

pls help me.

Although i3 3220 only for pci e 2.0, but for example from this video and other vids on youtube they are using i3 3220 with hd 7770 but mostly using mobo that have pci e 3.0 slot. From their spec, none of them using h61 mobo and i afraid when i buy hd 7770 using h61 mobo will be not 100% compatible. http://www.youtube.com/watch?v=bgqGmk8IURk

The HD 7770 will work on that mobo, but at PCIe 2.0 speeds instead of PCIe 3.0. Don't worry about that though, because the difference is mostly negligible.
