Right now I'm not recommending Intel CPU's.
Recommend a change from 4690k to 4790k is a even worse idea. I'm running a 1080TI too, with a 3770K @ 4.5, SSD and 16GB DDR3, I play @ 5760x1080 and right know there's already a simulator that is completely bootlenecked by this DDR3 platform, even at these resolution! Assetto Corsa... With 20 AI I get 50fps with my card running only at 60/70% usage.
I have assembled some PC's recently to my clients and the smothness of all DDR4 platform, even on desktop, is astonishing compared with my system.
Now, moving to DDR4 platform, there's another important fact... Right now AMD platform is much smarter choice than Intel.
If your idea was the 9600k, in Portugal for less 20€ you can buy a 2700x, that is 10/15% slower in games but crush Intel 9600K, sometimes by more than 50%, in almost everything else.
JRS was suggesting the 9900K, but for the same money you can get a 3900x, that once again, is 5% slower than the first in most games, but beats 9900K in almost all multithread operations by far, so...
For me, at the moment, AMD is the right choice for a CPU platform. I don't care if I only have 100fps instead of 105fps, if i'm faster in everything else.
That's my 2 cents guys
