I haven’t thought about it in a while but the premise of the article rings true. Desktops are overall disposable. Gpu generations are only really significant with new cpu generations. CPUs are the same with real performance needed a new chipset and motherboard. At that point you are replacing the whole system.
Is there a platform that challenges that trend?
Technology moves on. The highest spec iPads blow away older workstation class pc’s for non-gpu loads. It would only be the OS holding that back, not the hardware.
