its biggest problem with pc gaming, instead of consolos wich is all same, and u can easy fix all stuff at once, u have countles number of pc variats and if u use 4000 dollars pc, noone expect somone to use those highend components, i mean it works /sometimes/ but u get better optimalization for most used parts of pc wich means gtx 1060 would work best cus is mostly used, while when u get gtx 2080 u maybe get worse performance than with gtx 1060
also some components are alergic to each other ie sound card will disable your monitor…
