thanks for stopping by.
If you tower works you can go cheap with 2 cards.
low cost I have used ones for sale if you are usa based
https://bitcointalk.org/index.php?topic=5295633.0the evga 1660ti are okay and cheap from a good seller (me)
new they are 300 and a bit costly
https://www.newegg.com/evga-geforce-gtx-1660-ti-06g-p4-1667-kr/p/N82E16814487446?they do 25-28mh each so 2 do 50mh which is about 50 x 3.2 cents = 1.60 a day you will burn about 350 watts or 8.4 watts a day
so 8.4 x 10 cents = 84 cents in power 1.60- .84 = 76 cents profit
so buying them new for 600 means 600/.76 = 789 days to break even
buying them used for 300 (from me) 300/.76 = 394 days to break even
other cards that are cheap that should be okay
new from newegg
https://www.newegg.com/asrock-radeon-rx-5500-xt-rx5500xt-cli-8g/p/N82E16814930039?that is a 200 dollar card
it does 25-28mh and uses less power then the nvidia
so same 50 mh with 2 but power will be more like 250 watts for the rig or 6 kwatts or 60 cents at a dime
so 50 x 3.2 cents = 1.60 - 60 = 1 dollar a day
2 cards for 400/1 = 400days to break even
All of the above is based on your rig fitting 2 lessor cards in and 10 cent power.
2 used 1660ti 300 out of pocket buy from me
2 new 1660ti 600 out of pocket buy from newegg
2 new 5500 400 out of pocket buy from newegg
