Why is it that consoles life cycles last like 6-8 years but when people ask about future-proofing pc parts, the answer is always something like only several years? I want to buy a gaming pc that includes "top of the line" parts, but that will also last me as long as a console's life-cycle? Will a "top of the line" pc last me that same amount of time if the trade-off is that I will have to run games at much lower settings in the distant future?
