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?
Edit Good points were made. There is a lot to disagree with in the article, especially when focused on gaming.
Storage For the love of your data : storage is a WEAR component. Especially with HDD. Up until recently storage was so cheap it was crazy not to get new drives every few years.
Power Supplies Just because the computer still boots doesn’t mean the power supply is still good. A PSU will continue to shove power into your system long past the ability to provide clean power. Scope and test an older PSU before you put it on a new build.
I’d say that now is one of the strongest arguments for upgradability. Memory is really expensive right now. At some point in something like 1-3 years, it will probably be considerably cheaper. If anything, CPUs and motherboards are expected to be cheaper during this period due to reduced demand for new PCs. If you can tolerate less memory now and want to save money, upgrading then would be a good idea.
