Far from it. I have a very expensive Threadripper 24 core CPU + GTX1080 KFA2 HOF those 2 alone cost around £1500 plus another £2000 on the other high end components & 49" HDTV. I bought an X1X about 4 weeks ago. Nearly every single game I have rebought on it which I already owned on PC actually looks better, loads way faster & is an overall better gaming experience. X1X will if anything replace PC gaming in the short term as for just over £400 you have a very capable 4K gaming device. A decent 4K capable PC will cost you around £1.5K minimum if you want HDR as well then £2.5K minimum. On X1X if you have a HDR display its default in many games which on PC lack HDR altogether due to Win10 HDR DRM (you must have an Intel IGP GPU as a minimum for HDR on Win10).
GOW4 if you own on Win 10 it will also let you download the X1X game as its a Play Anywhere title so you already own on both platforms. But IMO the gameplay is very poor & boring although it has HDR on X1X & looks a lot nicer than PC due to that & more patch fixes. Win 10 version is not really updated anymore.
Then could be a surprise Windows Mixed Reality Headset support announcement for E3 maybe?I doubt we'll see any games above 60fps in all honesty. As you say, the CPU is too weak for anything above 60fps really.
It might render the dashboard really smoothly though
