So i've been doing research so I can purchase a new mobo. One thing that i've come across is that various z77 with a third x16 slot are showing as either pci-e 3.0 or 2.0
For example
http://www.newegg.com/Product/Product.aspx?Item=N82E16813131819
This asus has the third showing as a pci-e 2.0 x4
But if you look at
http://www.newegg.com/Product/Product.aspx?Item=N82E16813130643
This msi has the third as pci-e 3.0 x4
Is newegg just using the 2.0 and 3.0 interchangeably or is this really the speed of those mobo pci-e slots? I remember seeing the layout of the z77 and dont remember any mention of 2.0 x4. But I dont remember seeing that the z77 has x8 lanes of pci-e 2.0 which = pci-e 3.0 x4.
Anyone have a definite answer on whats going on with this?
