Updating Bought Hackintosh from OC 0.6.4

Hello all! I recently bought my friend's PC which I found out is a Hackintosh running macOS from one SSD and Windows from another SSD. However when I tried using macOS I noticed it started being unstable and the display would hang for several seconds that I needed to restart it. I asked him about it and he said I might have to update OpenCore, as he had never updated it from 0.6.4. How would I go about this? I saw that OpenCore is at 0.8.3 so my version is far behind. I'm worried I might break something if I try to just read the guide cause many changes might have been made.

These are the main computer components:
* CPU: Ryzen 9 3900X
* Motherboard: Gigabyte X570I AORUS PRO WIFI
* GPU: Sapphire Pulse RX 5700XT

Thank you guys in advance!
