Somewhat of a false argument. I had the 9900K from 2018 to 2023...Should I have accepted nearly 5yrs of lower performance with the AMD promise of a higher performing upgrade option (much) later down the road?
I'd argue the majority of PC gamers are far more likely to want to build a whole new rig after 5yrs, to take advantage of other tech upgrades available, besides the CPU & GPU, such as faster storage and new Motherboard standards.
In other words, buy the fastest you can afford to start with and enjoy that. Let tomorrows faster stuff take care of itself.
