No i am not taking MSI`s word over Gigabyte`s, its a fact! PCIEX GEN3 has to meet certain standards(not made up by MSI), and motherboards have to have certain components to be able to be GEN3 certified, and the Gigabyte boards(apart for a couple of models) dont have them. Simple as that!
Unless you know exactly what is needed for PCI-E 3.0 to work, you are taking MSI's word that the chip in the GB mobo will not work for PCI-E 3.0. You cannot have any CERTAINTY whatsoever about this unless you know what you are talking about, and neither you, nor I, and apparently most of the others from the forum have any experience with this kind of stuff.
I'm not saying what MSI is saying is FALSE, I'm saying it isn't necessarily TRUE. Until we have more info, we really can't judge.
I just wanted to throw this in here for all GB haters (I'll be talking lga 1366 as that's the only boards I know): Which board is better, Gigabyte's X58A-UD3R or a similarly priced X58 MSI board? I think the GB is the clear winner. So no, not all GB boards are garbage, just as not all MSI boards are garbage. Have some respect for both brands, don't just suddenly say: oh MSI godly GB garbage.

yes I know wiki can be wrong, but in this case wiki is right so it doesn't matter for the matter at hand
