You can absolutely get away with 12gb, 10gb, even 8gb vram and play 4k high refresh rate. But also doesn't account for poor programming. I remember a reddit post about God of War using 15gb of vram after a while of playing, probably a memory leak. Having available vram just gives yourself headroom for newer games with higher quality textures, there was a game which name eludes me which shipped with 8k resolution textures for 4k gaming so it used like 10gb of vram? Or something along those lines. But it can also be used for pre-caching stuff, like if you were playing WoW and the next zone was already precached so you don't need to load it from the disk. I think that new tech Sony and MS were working on, direct storage access? Will play a bigger and better role than higher vram. I only game at 1440p so I don't care for more than 8gb of vram.
