major usage?
If gaming, what games, resolution, setting, fps?
Budget?

Mostly gaming and running some programs like Fruity Loops as thus far. Overwatch GTA PUBG Rainbow 6 Siege Destiny 2 and some more first person shooters. 1980 x 1080. Nothing lower than high graphics (exceptions on alpha state games). 60 for lowest fps. Yes living in the U.S. Budget is around $500- $800
