For all those overclocking their D3s: The increase in profits with overclocking vs electricity usage is generally mutually exclusive!
There is an important caveat with this that should be mentioned: Do you believe in crypto?
What I mean is, a few years ago a friend of mine was obsessed with tuning his GPU rigs for energy efficiency over performance, his mantra was that if it makes $5 less a day but costs $9 less then that's like a bonus $4, I didn't bother with that as I believed in the coins I was mining/hoarding. I won in the end because his $9 a day saved is still $9 a day saved, but his $5 a day lost is now $200 a day lost because that lost crypto has risen in value.
