Nah. 144hz is the keyword there. I had a similar setup and went from a 1070 to 2080 so I can be above 100fps or use ultra settings in games that I otherwise couldn't. Playing at or around 144hz with everything on ultra is so worth it, where before games like AC:O would dip down to the 50s with settings adjusted. I guess "waste of money" depends on what you want your gaming experience to be and is very subjective. I personally think 4K is a waste of money and that gaming should be focused on 1440p instead of pushing 4K everywhere but that's just me.. I like 120+fps/Hz over a resolution bump when 1440p is typically pretty golden even with just FXAA. EDIT: Boy PC gaming has become spoiled. I remember back when everyone was just aiming for 60 FPS on Crysis lol. Good time to be alive for gaming I guess EDIT 2: Just want to make it clear that I don't think 4K is stupid or useless, I just think gaming should be pushing to 1440p instead. Especially consoles... they can barely sustain 60fps in most games.
