On some games you'll be able to get 60fps (and more), on others you'll need to tone down some details to achieve that result.
I'm not going to comment on your build since you got lots of expensive stuff there so I guess you want those (like 300$ case, fancy keyboard and so on
If you want to state which games you'll be playing that will be more helpful.
Yea, I know I'll need to turn down some games, I'm fine with that. I'll just be playing some racing games (dirt rally, assetto corsa), some popular titles (GTA V, PUBG, CS:GO, rocket league), and an assorted amount of other games (beamng drive, etc). I'm willing to turn down to high/medium settings in some games, for the 60+fps. I got that case because I wasnt sure if I could comfortably mount all the fans I was going to have; I'm definitely willing to change the case. The keyboard too, I just want a decent quality one with some backlighting. Thanks
