What size monitor should I get for this gaming build?

NiCoM

You didn't post the build link. ;)
Though i can already say 1080p/60hz maybe IPS panel (gives better colours)
Maybe 1080p/120hz if you're a FPS type of gamer, and are ready to take settings a single tad down to reach ~120fps

The build link would be nice so i could take a look at it :)
