I have disconnected my old graphics cards from mining and have already sold about half. In January, sales were bad, but in February I sold a lot of video cards.
If interested, I will write the sale prices
GTX 1070 $150
GTX 1080 $210
RX 480 8 GB $100
I did the maintenance, cleaning, replacement of thermal pads and fans myself, so my expenses were minimal.
I plan to sell the remaining GPUs in 30-45 days.

I still have the RTX 2070 and RX 5600, and while they are in the mining.

I keep thinking about what to buy.
I definitely don't want an RTX 3080-3090 and I certainly don't want an RTX 4080-4090 because they are so hot.
But I see that new coins require high performance of the video card core, so the 4xx series outperforms the 3x series on many coins by 50 percent or more.

If you make a decision on this logic, then my choice is the RTX4070 that should appear or the RTX 4070ti.
Or buy used 3060-3070.

RTX 4070s are still expensive, I can buy a 3070 after mining in good condition for 400-420 dollars.
Tell me your plans
