New, the X-Box 1 X. Expensive at $499. Powerful, plays the existing X-Box 1 games, but at much higher resolution up to 4K.
Deceptive advertising given that the newest titles, such as Ark Survival Evolved, are going to look like crap in that resolution. No console is capable of getting anywhere close to 4K resolution on the newest open world games or the epic quality of 1080P. You need a top end PC for that.
In all fairness, all games will look a lot better given the 40% increase in processing power of the graphic card and additional system ram.
