This probably has come around couple times but I'm ahving trouble finding any benches for 4 cards setups.
So to the point:
Is there and how much performance hit when running 4 cards at 4 slots at PCIE 3.0 with speeds x16/x16/x16/x16 vs x16/x8/x8/x8
Most of tests are done for up to two cards, wondering how much if there is any performance hit is with 4 cards, running triple mon setups or 4K resolutions etc.
Thanks!
