How many years or months do the GPUs last before they become obsolete (in mining)? Of course I know there are no real dates or a way to be sure of this but maybe an approximation? Im thinking of buying 2 vega 56
When buying GPUs the average people have used to calculate ROI return on investment is 10 months. And useful life I've heard of someone saying 2 years. But NVIDIA is supposed to be releasing a new series of cards. But no one knows when they will release them. When they do it should have an impact on your existing cards ROI and life expectancy to the negative.
