HappyNinja1: By the looks of this game, I truly believe the mim would be atleast 16GB of RAM and possibly a GPU above GTX 980, just on the sheer mass of how big this game is.
Big game doesn't necessarily means that it will need 512Gb of RAM.
It all depends on optimization. Witcher 3 is a big open world game but it uses less memory than Doom 2016 and loads much faster. And it runs flawlessly on the laptop i'm typing this message on right now. With max settings. Now ROTT 2013 can have framerate drops below 27 sometimes then go as fast as 160 because of bad optimization, UE3 FPS running slow on i7-6700HQ/32Gb/GTX1080M...
Or people tend to bash Unity engine for being slow... sometimes games with very detailed graphics and a lot of textures run on total potato netbooks and games with graphics not far ahead of Atari 2600 having heavy frame drops and leaking memory like there's no tomorrow. Same engine, same version even.
Or that infamous Warhammer tactics game (or was it strategy?) with map loading times over 5 minutes for absolutely no reason (with minimal HDD activity and CPU pretty much idling).
Only time will tell. And 8GB of RAM is a plenty for many games (like 90%)
GPU: 1060 6GB or better
I doubt that this game will require 6Gb of RAM for 1080p. Over 4k - sure.
