PCIe 2.0 x16 Slot Running at x8

[Kevin Vega]

I'm looking to know if there would be any issues running a x16 PCIe GPU in the x8 slot on this motherboard? The board has 6 x16 slots but two are set to run at x8 and the other two are set at x4.

I'm looking to set-up a Rendering Computer for DaVinci to render out one-light 709 proxies for an offline edit from the Black Magic Cinema Camera, right on-set. Looking into about 4 CUDA cards on the motherboard at once.
