Its 22-44 cent per kwh here where I am. Using an example of a 4080. The wear usage doesnt make it worth it. unless your kwh cost is lower. 3-4 years to pay off a new 4080. While a 6080 drops. Best to use with 24gb model like a 3090 or 32gb 4090/5090s. If your kwh cost is 1-15 cent yes go for it otherwise keep the intense working hours off your gpu.
@NewstalkFM Co2 is food for plants. CO2 makes up 0.04% of the atmosphere. 99% human co2 reduction will do nothing. Manufacturing was offshored to places that build coal power plants weekly. Fools gold.
