I am limited by capacity(small) and power price (high).
The way I see it is if I run mine at 6mh/watt then 1000watts=6500MH.
If you run yours at 4.5mh/watt then 1000watts=4500MH.
Have I got it wrong??
In order for you to pull 1000 watts, you will need 33% (6/4.5) more equipment than he will so your initial upfront costs will be higher to buy the equipment.
