Imposible to know. It all depends on how the games are writen, how fast is you GPU and at what resolution and details settings you play.
For example "newish" games like Shadow of the Tombraider, Battlefield 5, Red Dead Redemption 2, heck even BF4 and Raiwob Six Siege already shown to have better 1% low FPS on AMD (when compared to the 9th gen and even some of the new 10th gen ones) mainly because of the extra threads. And thats whats define for me how good or not is your gameplay. You could get away with 90FPS AVG with a CPU, but if the 1% low are around 45 ~50 FPS the gameplay experience wont be nice.
In the near future, you can probably upgrade to a Core i7 9700 or even better a i9 9900, thats if you feel the need. In fact I would...
