Fallout 4 doesn't really need much in terms of GPU power, being based on the same engine Skyrim ran on in 2011, when the top of the line card was a GTX 580. You can safely turn off NVLink/SLI for Fallout 4 or Skyrim because it tends to cause more issues with the games than it does improve performance.

 

CPU power, especially per thread, is much more important for Bethesda games. If you have a CPU with lots of cores, chances are those cores will be slower and the game will suffer, but you can tweak the game's INI files to take advantage of those cores better (Google "Fallout 4 tweak guide.) A recent i5 or i7 will have really no issues running the game except in some really dense areas; the way the game engine works, it's constantly processing scripts and especially will chug if you have a lot of mods. My machine has a GTX 1070 and an i5-6500 and runs the game fine at 2560x1440; I only really drop frames if there's a lot of NPCs around.

Fallout 4 is also not that well-behaved with ultrawide displays or with nVidia Mosaic. It can handle standard aspect ratios like 16:9, 16:10, or 4:3 just fine.

 

Microstutter is always a problem with Bethesda games as they tend to inconsistently load areas. Running the game from a fast SSD, turning off the built-in vsync and using the nVidia control panel to set up vsync instead (fast mode works particularly well in my experience for Fallout 4,) and adjusting uGridstoLoad to something like 24 in Documents\My Games\fallout.ini and falloutdefault.ini might help reduce the loading stutter (be aware that this drastically increases Fallout 4's RAM footprint and it won't address more than 7.25GB without crashing.)
