It should work but not always. There have been some issue reported when using very old motherboards with
very new GPUs. Sometime a BIOS upgrade helps with compatibility. There is a recent thread discussing this very issue.
It will either work or it won't, performance is not an issue. The only way to know for sure if that motherboard
will work is to try it or find someone who already has.
Thanks I’ll keep that in mind. It back to the drawing board for me consider the lack of support from the stock power supply. So that eliminated the 3090 as an option. I would appreciate any suggestions you may have regarding graphics cards that would suit my PCs current specs. That you think might allow me a bit of ETH mining. I believe highest electricity rate I’ve paid is $0.09 kWh so I’d like to explore the whole mining this. I guess I’m late with ETH staking potentially happening this year but it would be nice to get a shot while I still can. Thank for your time
