Unless it's cards, the original Doom, Avoid the 2400G which is known for game crashes and I've yet to hear that issue is solved. If this is for games BOTH would need a much better video card. So which would game OK with say the 1050 Ti or 1060?

According to https://cpu.userbenchmark.com/Compare/AMD-Ryzen-5-2400G-vs-AMD-FX-8320/m433194vs1983 that would be the Ryzen 2400G equipped PC.

At least you can fix both models later.
