And whatever happened to AMD's magic frame bufffer efficiency that was supposed to make 4GB HBR as good as 8GB DDR4? Don't ever believe anyone if they tell you a lower framebuffer is as good as a higher one. With every GPU coupled with a deficient amount of VRAM, AMD or nV (and their army of schills) purport they have some sort of voodoo that nullifies the issue -- and it never does. EVERY. SINGLE. TIME. Same thing happened with 4870 256MB, 7800 GT, 780 ti 3GB, GTX 970 3.5GB... Don't believe it.
