Hey. I've done a bit of research and found out that the first VQTech release (EMC1) looks quite perspective.
Especially, their low rate of power consumption 800 W and such a high rate of hash rate ~2850MH/s on Ethhash.

But it could also fit the rule of thumb is 1000:1. I think it would be better to wait for real-world tests and someone shares with you a complex argument. Because, if you aren't interested to be in the list of takers risker with no paying off investments,
you should know a lot of positive feedbacks from the real users.

Hi, guys!
Wanna know your thoughts.
What do you think about the best mining rig for Monero, GPU or FPGA? If you want any suggestions about types of equipment, I would be glad if you shared it with me.
