Since you don't have any preference, high-end GPU such as RTX 3070/3080 and RX 6800 are best option. But AFAIK it's hard to look for those GPU due to various reason such as cryptocurrency price rise in last few months.


This is good website, but i would suggest OP to do further research because altcoin price are unstable. IMO looking at price history on last 7 days isn't good enough.
