Why do most people game? Entertainment, stress-relief, socialize, spend time with friends/family.
Why do most people mine? For profit.
Why do people quit gaming? Life. Addiction. Disability. No longer entertained. Can't afford it.
Why do people quit mining? No longer profitable. Too much stress dealing with volatile market. No longer entertained.
I am about as heavy of a gamer as they get. I use one card at most 16 hours per day and it is very rare for it to hit and maintain 100% load because vsync is enabled. You're a casual miner using two cards that are collectively worth about four times the value of my one card and you're running them 100% 24/7. In terms of economic resources, I consume substantially less yet arguably get much more value. You're making what, $3/day now? Yeah, I definitely get more than that in terms of stress relief.
