I just temporarily unemployed and on my expensive devices have no money ... The only thing I bought this graphics card, as it was necessary ...
You can squeeze nothing out of them. Especially nvidia cards, they do nothing. Just don't get into mining, Bitcoin isn't a get-rich-quick scheme, OK? That U1 will get you a max of $1 per month, and the GTX 770 even less, so don't even bother.
