Via Steam, Uplay or Origin?
What types of gaming do You like?
First person, third person, campaign with a story or online multiplayer-games or?
To be able to take it to the task, I can recommend several very good games that will last for a while. And don't forget the side missions on either!
GTA-V, Maffia 3 and not to forget the old Crysis 3 ( from 2013 which you can get at a very low price at Steam) - yes at its highest settings your rig will barely go beyond reasonably fps.
Not to mention Far Cry 4 - which you can play with different outcomes, which choices you make in the game depend and also take help from a friend or other. Comes with an inbuilt game editor as well.
