I'd rather be careful with Fury's vram limits then be able to use 8gb vram and it not be playable. Also, while i am not technical on vram usage and limits in knowledge. I have found that fury always seems to allocate less and i am able to up settings based on raw performance over the 390x. When using MSI ab on 390x in DAI i see around 4.3gb usage and in cut scenes its gone as high as 5+gb. and fury with exact same settings shows 3.2 - 3.8gb usage. I can find limits to Fury's vram if i try which is possibly a killer for people looking to future proof.
TDLR: 390x 4gb+ usage fps is too low to care(4k+). FuryX sub 4gb usage unlike 390x and i am able to use higher settings due to raw power. Can easily hit limits of fury vram which can be a turn off for people looking to future proof.
The information is mostly my opinion for my usage, but thought i would share in case people are wondering.
a minimum of 2 390Xs is needed for 4K as you find out, then the vram becomes a non issue. at least with the games today.
edit: not sure if they updated AB in the latest version but with my hawaiis, it measures vram usage using global output. meaning it add it up. so, for 2 gpus, you need to divide the figure by 2. i use HWINFO and that too adds up the vram usage.
also, FuryX is easily 30% faster than 390X, so you can't use same settings in games. if you are - i mean.Edited by rdr09 - 10/16/15 at 9:57pm
