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.
