PCIe3.0

Intel lists PCIe 3.0 support in the chip's datasheet but is publicly guaranteeing PCIe 2.0 speeds.

PCIe is forwards and backwards compatible, and performance drops from going to a lower PCIe revision aren't really noticeable until you go down to something like PCIe 1.x x8 for most cards.

So yes, it's fine.
