So my friend had his RX 580 die on him so he went out and bought a 3080 12GB for around $650sh USD once converted. He did also buy a Lian Li Lancool 2 case along with 850 watt PSU since his 550 Watt is not a good idea with a 3080 loll.
The interesting thing though is even though he has a 6600k, his CPU cooler is loud af with a 3080 compared to his 580 mainly due to the cpu usage has gone up significantly. Granted his CPU cooler is the Hyper 212 Evo but still, it's something that I didn't really think about. He will wait till Zen 4/Raptor Lake before upgrading though and while he was hoping to get Lovelace instead, can't do much when your GPU dies.
