Question / Help Recomended Settings? (PC Specs/current settings listed)

[NeverLie]

So I currently recorded in 1080p 60fps and its pretty good ngl, but I kinda want to upgrade to either 1440p 60fps, 1440p 120fps, or 1080p 120fps, or at least have the option to. I mostly play Minecraft on a modified client called "Lunar client" which was developed to prevent MC cheaters.

PC Specs:

OS: Windows 10 Home 64x
CPU: Intel i5-8600k 3.60GHz 3600Mhz 6 cores
Motherboard: Asus TUF Z390-PLUS GAMING (wifi)
Ram: Kingston HyperX Fury 16.00 GB DDR4 2666Mhz
GPU: MSI GeForce GTX 1050 Ti 4gb of dedicated VRAM

Current OBS settings (I don't stream so only rec settings):
