Need Some Assistance

[HawkinsonB]

Hello all, i'm looking at adding a new monitor to my setup. I currently have an Dell U3415W that i use for my main display(this is driven by a 980TI). Now i'm looking at adding another monitor(or two) into the mix. 

What I do daily

 

-Coding - compSci student

-Photoshop/illustrator - photography/graphic UI design

-gaming - LoL, minecraft, World of Warships, Software Inc, Cities Skylines, Offworld Trading Company, i am thinking about pllaying shooters but it's still up in the air. 

 

what i'm on the border with: 1080p vs 1440p

144hz vs 60 hz?

24 vs 25 vs 27 inch monitor?

 

let me know what you think, my total budget is about $400

 

Thank you for your input
