Oh it's from AOC!
Yes this is probably good 
Either way both are good and it depends on what the OP goes with 

A  freesync display will work with it 
But I'm not sure if free sync as a technology will work 
But don't quote me on that 😅

this is similar and i've heard good things about it. although it ia 1080p

I have seen this monitor a couple of times 
https://www.msi.com/Monitor/Optix-Mag241c
It's va with srgb coverage of over 100%
And 1ms with pretty good color reproduction at accurate colors and I think it's 1080p but if I recall correctly there is a 2560x1440p model of it so do make sure 

Honestly high to ultra for the 1660 super is pretty easy 
What's no lt easy is 1440 hz
Over all I'll tell you how they stack against each other so you can decide
 
The 1660super (around 230 dollars give or take ) it performance  basically the same as a 1660ti (it maybe is 2-3% slower ) but has that higher bandwidth memory buffer so it will be more future proof while being cheaper than the 1660ti 
 
The 1660ti (280ish give or take ) don't even consider it.
 
The 2060/super (around 300-350 give or take ) it performs the best obv and it has dlss and ray tracing (as you know ) 
Now all of these cards can handle 1440p but the 2060 can handle 1440p at a little bit of higher frames 
But I'll suggest something : the 5600xt 
For 280 dollars it is WAY cheaper than the 2060/super and performs pretty close to them so I recommend it over the 2060 unless you want to skip the driver issue with amd or you want dlss or something 
 
 
 
 
Now for monitor , are you willing to go VA because VA brings pretty good colors (not as good as ips but better than TN ) and it is cheap 
So would you go VA ?
