Xbox One X is a $499 console that's doing 4K and to most people that have seen this video they think the Xbox version looks the best.
The PC version is running on a Vega 64. The Vega 64 alone cost as much as the Xbox One X.
Like the PS4 Pro this is just a mid gen console refresh. Can you imagine the visuals these consoles will do when the true next gen PS5 and Xbox Next launch in a couple years?
