I might be wrong but... I don't know, how jumping to i7 would really help to be honest. I mean, from what I have read, Skyrim and Bethesda RPG-s in general can't really utilize many cores but more like clock speed alone and i5-7640X seems to be the best way for me to hit high clock speeds with reasonably priced CPU (With a cost of the relatively low amount of cores. ). When it comes to GPU VRAM - it seems that in every case, GTX 1660 has 6GB. I'm also not sure if you have caught my understanding of "4K" here. Now - I might sound like a total idiot (That I very possibly am. ) but I don't want to go over the 1920x1080 DISPLAY resolutions. I mean - even on 1920x1080 display - I would see a difference between 2K and 4K texture sizes if I'll be staring at a wall or a bark of a tree or something (That I sometimes do just because I can. ), right? It's not like installing 2k textures has no sense without a 2K monitor so I assume that it will be the same in case of 4K-sized ones. When it comes to textures that occupy big spaces, the difference in their look in close-up would still be quite noticeable, I would say. It might be obsolete on textures madefor smaller surfaces like armor or something but when it comes to terrain... Anyway, please tell me if any of my statements (Either about the type of CPU or usefulness of 4K landscape textures in my case. ) are false or naive. Sorry, I had to edit because of ugly spacing.
