Fallout 76 on PC is lenient on GPU requirements, but you'll need a decent CPU to run the game from the Bethesda.net client.

Although Fallout 76 shares a lot in common with Fallout 4, it's a lot more demanding PC spec-wise. According to the new Fallout 76 PC spec announcement the online-only service game puts more emphasis on CPU usage. Gamers will need a rig outfitted with at least an Intel i7 4790 or AMD Ryzen 3 1300X CPU to play, but the GPU side of things are more forgiving and require an NVIDIA GTX 780 or AMD Radeon R9 285. The standard 8GB of RAM is a minimum requisite and the game clocks in at 60GB.
Recommended specs are the same CPU-wise, but Bethesda advises an NVIDIA GeForce GTX 970 GPU or Radeon R9 290X with 4GB of VRAM to play Fallout 76. I'd like to see a preferred or required internet connection speed advisory on here too (remember Fallout 76 is purely an online game).
Fallout 76 will release on November 14, 2018 for PS4, Xbox One and PC.
