I use this rig mainly for gaming
It has ran every game I've thrown at it so far including:
PUBG Rainbow Six Siege Arma 3 Witcher 2-3 Fortnite
I fixed some settings but I kept all the main settings on the max and im getting a solid 60 frames on everyone of them, PUBG settles in about 3-5 seconds after you land and its smooth from there with picking up items without delay.
Finished building this guy on christmas and been using it everyday with 0 complaints.
p.s. the case sucks for cable management ;(
