Okay so I'm going to buy a new monitor. I'm not sure what I should get. I really can't choose going for 1440p 144hz or ultra wide. These are the monitors I've selected for the 3 categories. Here in the Netherlands they are all around the same price range. I would really appreciatie your input.

You've listed a benq there at 560, you can get a Asus MG279Q got 500-590 thats 1440p 144Hz IPS (about €600)
27" 1440p is a nice size. You could get something smaller 1080 at 24" (seems to be a size your looking at?), but personally I wouldn't bother with ultrawides, I also wouldn't bother with anything thats not IPS, because whats the point?
yeah I can get the benq for ~€300 here so that's why it's in there the asus is out of my price range. I was looking for a bit bigger then 24" but couldn't find one in my €300 price range :)
