Noob question: Mining with a LHR 3060ti AND a super old GTX 670? Possible or stupid?

So i'm a total noob. First question, my Mobo have 2 PCEI 16x slot.

And when i check some website, it say that the GTX 670 could make around 7.8 MH/s for ravencoin ??? https://www.betterhash.net/NVIDIA-GeForce-GTX-670-mining-profitability-174.html

Or like 60$ per month with a other "I don't kknow" coin? lol https://www.gpucheck.com/profitability/nvidia-geforce-gtx-670

Are these website just out-dated/Bad?

I'm a total noob, so i think i find/go-to weird website lol.

I try to see Nicehash with my GTX 670 only ( i didn't install the new card ). And my GPU is not supported.

Will it work on 2miners ?

Or i can just try with NBminer ? ( I'm not sure if we can you NBminer alone, or it need nicehash or 2miners? ) I don't get the "miner -> pool" thing. If you have a good website that is simple to know the base. Would be cool

( My end goal would be to be able to mine directly to Coinbase of payout, Binance for trading, and/or my own free wallet ) When i install my 3060ti LHR later-on
