Unfortunately, there will not be a way to test what the true results are on the amd platform until we see either a chip with at least 32 pcie lanes dedicated to gpu's or a motherboard that will utilize a plx/pex chip.

Having said that, I would find it unacceptable to give up performance anywhere if I've invested in a pair of 1080 ti's or TXP's.

Yeah, I know it's a lot of conjecture, but unfortunately I'm not even sure if the different platforms are capable of handling PCIE lanes in different manners .
