Division 2 and latest assassins creed games will bottleneck. Still smooth, but it's happening already the move to 8 or 6/12.
Can't speak for Division, as it's not my sort of game.
I played Assassins Creed Origins and Assassins Creed Odyssey all the way through, probably 100 hours in total, as I love those games. I was not expecting them to perform well at all on an overclocked 3770k, but they both played perfectly fine. Sure, the 1080Ti was helping, but even so, I was surprised just how well my Ole Clunker of a CPU handled them.
