I thought it was something like this.

Personally I wouldnt recommend it due to the massive price difference between 4k 60 and 4k 144, as I said it is not something you notice unless you already play at 144fps which makes going back to 60 a bad experience. It is not something that results in a significantly better experience in that sense, sure playing at 144 is nice, but it is not something you notice as much as having better graphics (again, this is subjective, I personally have an 144hz monitor but I do play a lot of multiplayer games, and even then sometimes I play at 60 fps if it means significantly better graphics on single player games)

The best possible thing you could do is go to a hardware store that has monitors on display or ask if you can try it and see for yourself the difference and if its worth it, but as an abstract idea without knowing you personally I would recommend going for a 60 hz monitor, especially since you could allocate that difference in money to other parts of your build or peripherals.

And even if you were to decide to play multiplayer, believe me the difference is response timing is not that big and once you get accustomed to it your brain kind of gets used and starts predicting things geared towards that framerate, neglecting some of the advantage of higher framerates, I believe this idea was on a Linus Tech Tips video a few years back they did with Shroud, dont know how true it was but its out there if you are interested.
