Well now that that merge is upon us. I will be focusing on other PoW coins. In this case Flux. The RTX 2060 Super along with the rest of the 2000 series is solid on flux and if you are still buying cards worth a look at the right price. It is a great mining card at 45 Sols.
2080 Ti Mining Overclocks - Power Limit (%): ~70% or 150 (W)Core Clock (CClock): -200Memory Clock (MClock): +1100 or 2200Fan Speed (%): 70% ± based on your temps.
The GTX 1660 Super in my view is still a great card for beginners to mining and if you can get hold of it for the right price it's a good starter if your new to mining. As this only requires once power cable into the GPU.
