Everything will work fine.... but it may suffer a little memory bandwidth issues which is almost negligible..

PCIe 3.0 is backwards compatible with PCIe 2.0. PCIe 3.0 is twice as fast as PCIe 2.0, eg PCIe 3.0 running at x8 is the same as PCIe 2.0 running at x16. Current GPU's do not saturate the lane at PCIe 2.0 x16, so you'll be fine.
