for other algos then all scales pretty the same so you can chose if you want density for a premium or if you want lot of rig to administer and pay a lil less
If you have more rigs, that means you're paying for more motherboards, CPUs, RAMs, racks and power supplies.
It might be more cost-effective to get more expensive cards.
yep so now im stock with 6 1060s or 3 1070 plus 1 1060 since it will cost the same here in my country
