These are very simple games in terms of graphical intensity, and your pc is pretty basic in terms of gaming prowess.
3000$ is enough to get a PC that is 10X greater and a sick monitor, you do not need this much.
If all you want is a bigger monitor, play on your tv or get a new TV.
If you want a normal desktop monitor, and care that the games look as sharp and as colorful as possible, look for a monitor with good color calibration out of the box, and one that support HDR (though I am unsure your games support it.) with a peak brightness of atleast 600nits and an HDR600 certification or higher
high refresh rate is also nice, but probably won't matter much in these basic, slow paced games, so would resolution not help much.
If you want to go all out, you can, but to be honest, the cheapest IPS panel that is a good size for you would work <---
