What are the best GPUs for mining altcoins? isn't it odd that there are GPUs priced at $1000 and even more but when you benchmark them you'll see that for mining they are not worth a penny

Mining has almost NEVER had a use for the high-end cards.
They're all about GAMING.
Keep in mind that cryptocoin mining by the standards of AMD is a SMALL market on it's best day - and outside of EVGA and it's backing for FAH isn't even a BLIP in the market for NVidia.
That is right. I usually the middle cards for mining.
not really true a 1080 can do 535 sol now. even if it cost you $500 it's worth it
currently 1 sol for every $1 invested is a good compromise
Please lets not turn this into a AMD vs NVIDIA battle thread.
We are all bias and AMD people keep praising AMD
While NVIDIA people keep praising NVIDIA
Both have their uses and applications and its up to the buyer to decide which one is right for them.
