Hey there,
an update of my previous answer.
RVL/AVN was working great still hot. I switched the GTX970 to FLUX @ around 20 sol/s. Nothing special here but better than nothing.
Good result FLUX @ around 20 sol/s. You will get about the same result with the RTX 3050.
But the profit is very small, it is better to sell such a video card.
