I cant really be of much help on that topic, i still have the screen of the first pc i ever bought, its a pretty basic and very old, non hdmi screen, im still doing fine in most games i play.

That being said, having the best gear will certainly help in general, even more in newer or more demanding games.

Ive read that 75hz wasn’t worth it cause they stopped mass producing them so the price hasn’t lowered that much, that being said knowing which 144hz would be best .... good luck with that lol
