Max settings with ease..

Intel i7-6700K // 16GB Corsair Vengeance DDR4 2400Mhz // Zotac AMP! Extreme GTX 980Ti // Windows 10 x64

I get between 130-160FPS in Star Wars: Battlefront maxed out and that game while most of the specs are overstated has vastly higher specs than this. Expecting similar results in Fallout 4.
