The GTX 1080 Armor was an upgrade from my last video card, a GTX 680 Lightning. I didn't want to step up through all the video cards so I bought the 1080. I'm still happy with the way it performs. 7D2D isn't the only game I play and I get amazing results (Arma 3 etc) over the old 680. My last upgrade was the SSD which was the final upgrade for this 7 year old MB/CPU combo. When I stop being happy, I'll upgrade the MB/CPU. I've been doing it this way since my first PC (386 DX 33), buy very good components for that tech era and keep it for years.
I am aware that voxel games like 7D2D and Emperion are CPU intensive. I am also aware that the AMD CPU falls short on true multi threading. Next CPU will probably be an Intel.
