I am wondering if it is possible to put a Radeon RX 480 into a PCIe 1.0 x8 slot. BTW, the x8 slot has a x16 connector. I intend to use the card for GPU mining(feathercoin or ethereum). How much will the RX 480 be bottlenecked? There was a similar question, but it was about a PCIe 2.0 slot, so I do not believe this is a duplicate.
