I think i would like to try dual rx 480's when they come out. I have seen posts that say you can't saturate dual 3.0 pci exprees x16 but it was a few years old. I bet those rx 480 cards could though when they come out this month.

If you are talking about Skylake then b150/h170ms have 2x PCI-E x16 slots. If you want to run both gpus at x8/x8 then you will need a Z170 motherboard, since the b150/h170 boards provide only x8 + x4, however x4 is enough speed for the RX 480 so that will do the job.

I don't think a board like that exists for either of AMDs current platforms with full bandwidth for each card.

There are some mATX boards that have a 2nd pci-e slot that it routed through the chipset and is only wired for x4, it's also not recommended running xfire like that though.
