The best are the one you can get + that are not overpriced. Start by doing a google search and see which one u can buy... After that we`ll see. Why wasting time recommending unavailable card? The best are with Samsung memory, but company for the same model could use different brand. New rig might never see return on investment before a long time, easy money almost gone by now, you`re at least 4 months late.
The reason I'm asking mate is not because I need an advice on what to do but rather on how to proceed
I see lots of cards becoming available. It looks like the memory shortage is going to be over soon. The prices for RX570 now start at around $300 with immediate availability. I'd guess that 570 with $250 price tags are going to become available in a few weeks or so.
Again, the question is not about profitability.
However if anyone has any specific info on particular GPU models that he/she would like to share it would be much appreciated.
