That may not be enough so I'm giving the nod to the 1070 Ti.
I'm looking to upgrade my computer as it has been a few years (Subnautica is a bit choppy on max settings), and I'm looking for your advice:
Windows 10 64-bit
Asus Sabertooth Z97 Mark 2
Intel Core i7-4790 CPU @ 3.60GHz Quad Core 8MB 84W
2 X Kingston DDR3-1600 8GB
NVIDIA GeForce GTX 780 3GB (Quiet)
Samsung 840 EVO 1TB SATA 6Gb/s 2.5inch SSD
Fractal Design Define R4
Seasonic X-850KM3 850W
What would you suggest for an upgraded graphics card, and any other advice you have?
