Here are some of my suggestionsWhat are the most graphically impressive games in the last 3 years? I mean technical not art style, stuff that just looks amazing at high settings.
Shadow of the Tomb Raider:
Anno 2205:
Assassin's Creed Odyssey:
Deus Ex: Mankind Divided:
Prey:
Quantum Break:
Rise of the Tomb Raider:
Watch_Dogs 2:
Wolfenstein II: The New Colossus:
These would keep your GPU busy.
