I have a very expensive PC. Can't run in 4K 60, just 1920x1080 in 60?

My PC is very high end, but it can't do games like Assassin's Creed Origins in 4K 60 FPS. It can go to 4K but only around 25 FPS.

System specs:
Intel i7-5820k @3.30 GHz
NVIDIA GeForce GTX 1080
16 GB DDR4 HyperX RAM

Monitor is 3840x2160 so no problem with the monitor. Any help is much appreciated!
Also, apologies about the category. Didn't see one for gaming PC's.

seems that AC Origin is one of most demanding PC games rn,

benchmark of r7 1700@3.9 with gtx1080 hit average of 38fps @4k

motherboard, hard drive(s) and weather or not if it's running a raid. What OS? What resident programs are running (malware/antivirus)?

Need more info.

I just use windows firewall for the malware and antivirus. Running windows 10.

What about other games result in 4K? Demanding titles I meant.
