1 other thing to remember.....you can get a 1440p monitor and still run games at 1080p if you find you need more frames a second and still have it run in full screen.....1080p looks just fine on a 1440p monitor and i am saying that as i have a first gen Xbox ONE hooked up to my 1440p 32inch and it can only output 1080p as the max resolution from the console itself.....spending the loot on getting a 1440p at 144hz or 240hz now means you can scale each game to how well the system runs.....some games might do better at 1440p with a mix of high and ultra settings were as other games do really well at 1080p all ultra.....this will be on a per-game bases with no real magic bullet for all....but you know you will NOT have to screw with thinking about a monitor for many years to come going this way.....
if you are really going to drop some cash go big....the 31.5 inch screen size is not that much bigger then a 27inch in over all size the jump only gives you 2 inch more on top and about 1.75 inches on the side bigger then a 27inch
i got this 1.... https://www.newegg.com/p/N82E16824160314
i wanted a 10 bit monitor just for the other stuff i do as i have more then 1 computer hooked up to it....i cant go back to a 27 25 and and will only use a 22 inch for a second monitor
looking around just now its still really hard to get a 1440p monitor at 240hz so 165 might be a better option if you want this resolution as it cuts the price in half
lol this is the exact same monitor i have and i give it the highest recommendation. It is 1440p/31.5"/165hz/4ms/1800 Curved/Gsync. It hits all the marks. In my opinion it is the best monitor you can get period. If you can get one, get two. It's that good.
If you're wealthy then go 4K with at least a RTX 2080. If you're playing on a budget then stay at 1080p.
I'm playing on a 24in ACER Predator 1080p@240Hz G-SYNC monitor and it looks great at high FPS on my RTX 2060. You don't get champagne tastes if you never had champagne before
Do lots of research before you buy and check for dead pixels after you install the monitor. I found its best to buy local so its easy to return the monitor, happened to me with my ACER after I found several dead pixels so I quickly drove to Microcenter to exchange it and its replacement had zero pixel defects.
