Title pretty much says it all. Considering cost of acquisition only, what card currently available for purchase provides the best value considering only the cost of hardware acquisition?
if power draw is not an issue
then radeon vii is amazing at ethash
can hash at speeds 90 mhs at stock settings
in future with some tinkering to the bios it may achieve even 110 to 120 mhs
I heard same story for Vega....
