"Bandwidth has nothing to do with resolution, if you watched linus' test with 8x vs 16x, you would know." Maybe I should have stated that I was referring to 8x vs 16x, and not just "bandwidth has nothing to do with resolution" Sorry for the confusion.
I think I misunderstood you because you said get a board that's capable of 3 X PCI-E 3.0 16x, and the only capable board of doing that (as far as I know, even in x79) is the Asus P9-X79-E WS, and getting that just for the sake of running at 3.0 16x when 3.0 8x will make no difference at all is ridiculous, so I was arguing about that. Glad to know that you weren't making pointless recommendations and not someone who says "moar bandwidth is better cuz 3.0 8x is bottlenecking so much" like the 9000 people on youtube that I had to explain this to
Edit : forgot to quote you @Muramasa
