Strobing is an awful technology that not only introduces flickering, wich is bad for some eyes (including mine) but also adds double the input lag. I have strobing on my 240hz panel and I never use it. You don´t get my point. Is not about having 240fps! Having a 240hz panel and a framerate that fluctuates from 120 to 200 is already smoother than any 120hz/144hz panel even with Gsync/Freesync, because the monitor can actually display every frame without needing to lock framerate. The Motion Clarity is amazing, response time near 0,5 (closest as it can get to Oled or CRTs), and the input lag is half of 120hz! Even if you run 60fps at 240hz it will have half input lag compared to 120hz (just an example, I always try to run high framerates).
Having 120fps-200fps interval on games like Overwatch, Quake Champions, Dirty Bomb, Rainbow 6, Destiny 2 or Warframe, at medium/high settings 1080p, doesn´t require an unrealistic amount of juice! Requires a very good cpu for gaming yes! Something like the 8600k at 4,8ghz will do! Something Ryzen can´t deliver, otherwise I would have one! Simple as that. You need to understand everyone has different needs. I love my 240hz setup and I don´t want a CPU that will keep my minimum fps at 85 or 90, as you can see, for example, on today Steve BF V multiplayer analysis with Ryzen vs Intel highlighted.
Now you can argue that Intel CPUs are so expensive right now that it is madness to buy them instead of a Ryzen and I agree! 100%! But 1 year ago that wasn´t the case.
One thing I can warranty you, 240hz is not placebo and it really improves your experience on every game that is not a 2d platformer or maybe RTS! The persistence is valid even if you can´t reach close to 240fps, you don´t need to. When you move your mouse realatively fast even on a 3rd person RPG, having 240hz 1080p will provide better clarity and image quality while on movement even compared to 4k 60hz! Because there will be no distortion/smearing/ghosting. You should try one day and then you agree with me.
And remember, 240hz monitors go as low as 260€ nowadays on European Amazon. Is not a premium price.
