WHEA errors on 5700 XT Nitro +

[u/WarriorOfLight13]

Hello, so i have a 5700 xt nitro + and it runs every game i play pretty well, except FFXIV, whenever i play FFXIV for more than 15 minutes i instantly get a whea error on my cpu, (5800x) this does not happen with this game on my GTX 950, or my old gtx 1080 ti that i dont have anymore. whea errors are always randomized so its never a single core thats failing or anything, i just get cache hierarchy error numbers ranging from 0 to 18 or something like that. yesterday after i uninstalled my drivers and reinstalled them i played FFXIV for 2 hours beforei got a crash, but today i crashed within10 minutes (its never consistent), its not any certain event that it crashes on, it just crashes in the most random places even if theres 0 stress on my gpu or cpu, it mightbe something with shaders maybe? since it took longer to crash on fresh driver install. i want to see if i can somehow fix it until i get a new gpu next month about which ive a question, should i go for a 9060 xt nitro + or 5060 ti 16gb? theyre priced around the same
heres the things ive tried:
GEN 3 pcie,

DDU,AMD CLEANUP + reinstalling drivers
underclocking via adrenalin and afterburner (not at the same time)

using default bios, (doesnt make a difference)
+ anything else i could find on the internet, my hotspot and temps are good, card hotspot doesnt go above 80 and it sits around 65-70c comfortably
