Just built a new computer 3 weeks ago and got an RTX 3090 (I also do stuff other than gaming) from best buy two weeks ago. I currently have a 60hz monitor, but I currently plan on buying an upgrade to that as well since my old laptop had a 1080p 144hz screen and I used to play on that high refresh rate a lot. I'm not sure whether or not I should go for 4k 144hz or 1440p 240hz. I mainly bought the card for 4k and not for 240hz but I'm just wondering if going for 4k 144hz will be any use because of how much power that requires. Even if you bump the resolution down on the monitor to get higher framerates, it won't look as good as it does when playing at the native resolution, which is why I am considering 1440p 240hz. If I can go 4k 144hz, then I will do it because that will save me a lot of desk space and I don't really care much about the difference between 144hz and 240hz (if I do end up buying a 1440p monitor, I will still keep my current one).
