There's a thumbrule that goes around here. If you can afford a display that is say 1000USD, you should be looking at a GPU that's priced similarly. You should pair a cheap entry level gaming GPU with an expensive monitor. That being said what is the make and model of your display?
the monitor is for 319 and the gpu is for like 60 but my gpu is said to run 240hz at 1440p and 120hz at 4k, i didnt wanna spend 600 just to get 280 fps on "geometry dash" and i can already get 2000 fps about already with fps bypass. i just want a high refresh rate for clearness
btw that doesnt answer my question that just tells me to spend money.
2,000 fps is pretty much 2,000hz since hz is number of times a second the monitor refreshes the screen. However buying a 280 hz monitor for simple games is akin to buying a solid gold diamond crusted fork to eat a 30 cent cup of ramen noodles.
