Extreme bottlenecking - RTX3080 with a Celeron 1037U
Decided to stick my RTX3080 in that revived 2013 budget gaming PC. This was purely experimental - don't try this at home kids.
Definitely not recommending this. If you can afford an RTX3080 but have a much older PC and CPU, you are probably better off dropping to a 3060 or even something cheaper (2060 / 1660) to get a more recent CPU.
