Yeah I was exactly the same as you for years, holding out against what I considered to be unecessary exrtravagence. That was until I got a 4k monitor at work and experienced 4k HDR gaming. I immediately went out and bought an RTX 4070 and a 4k monitor and I will never be going back. The experience is glorious and I was a fool for not jumping sooner.
4K HDR gaming is not the future, is has been the standard for many years now for good reason.
