I have already found my next gpu solution in the form of two r9 390's, however to fully enjoy my soon be beast of a computer, i must first find a way to connect them to my 4k tv. Now the problem is my tv doesnt have a display port. I was reading an article {link below} stating that HDMI 2.0 can run 4k at 60hz refresh rate. Is this true and will this one off of amazon work? And will it work with my gpu's?
