I have some other rigs running but I am looking to building another rig so help me to choose the best setup for mining, 2x RX5500XT or a single RX5700XT? Which one will be better in return of investment wise, energy consumption and cost
I prefer lower power graphics cards because they have very few overheating problems and are more stable. But that doesn't mean you should buy any RX5500XT.
The RX5500XT 8GB will probably be easier to sell later, because they are cheaper and will suit many gamers.
The perfect middle is the RX5600XT.
Doesn't make sense to me because 2x RX5500XT is equal to a RX5700XT and the power is as follows
RX5500XT = 54 watts power draw mining ETH ( 2x = 108 watts)
RX5700XT = 91 - 100 watts power draw mining ETH
It's fairly the same thing and a RX5700XT still use 4MH to triumph over 2x RX5500XT
