Ledipaa, Your calculator is wrong. Two rx on eth in dual with dcr currently gives ~$90/month. While unstable working Vega 56 on monero ~85.
power used for 2 rx on eth with dcr vs power used for 1x 56 mining monero
I see claims with 140 watts for 2000 hash on vega's doing monero
I know 2x rx 470's 480's 570's or 580's will use more then 140 watts
so form factor a good board could do very well with vega 56's
I have this board on order. comes on monday
seems really good to run 4 vega 56's with endless spacing for cooling
but right now I am almost all nvidia mostly because of a few more coin choices
do you have the link for this?
the ones I can find on taobao.com are those with embedded cpu
