Please answer the question. I am also planning to make my own rig. But please answer it in simple way. Cause we know nothing about tech so please do not tell anything about down volt or tuning
Simple way: buy ETH and hold it gonna be more simple for you / us and everyone.
And with 560 if you don't "optimise" the card it gonna be not good at all.
I hope this is a simple way to answer.
