I am getting all my RX480s to hard labor now to max my available power.
My sources in Shenzen shared with me that come November, we may see a sharp drop in hash due to 4GB cards going offline. This should give us enough time to get ready...
If ETH goes ballistic hopefully I can source enough OEM 5700XT on K35s from Shenzen, before the herd comes in.
Think I got myself a partner who will be able to help with liquidities. I'm considering waiting another 6 to 7 weeks to see if 3070 is a better choice than 5700 XT though. Hope I won't be too late to the party.
Waiting for the 3070 is not a good idea.
You should consider doing 2 rigs
one with 5700/5600/5500
and then one with 3070 later.
If you are USA based. You can be mining by Tuesday the 8th

155+20+30+11 = 216 and you are ready for cards for rig 1 add 5 cards
1 in slot 1,3,5,7 and a short card in slot 8
easy peasy rig is running in under 35 minutes if you use 1 visiontek 5500 xt and 4 msi 5600 the 5 cards are about 1250
rig does around 188mh uses under 800 watts
then hold the gear for rig 2 and load up on the 3070.
This game is always about hedging.
Go all in on the amd = could be all wrong or all right
go all in on the Nvidia in 7 weeks = could be all wrong or all right
go 50-50 amd now Nvidia later = has to be part good. could be both good.
