The typical release cadence of PC components is around 4-6 years, which requires new motherboard, CPU, and RAM.
Not with AMD though. Usually the motherboard can be reused if you buy new generation of CPU and RAM (good luck if you have Intel, then you are screwed and need to change everything). But besides that, even after a few years upgrading graphics card and RAM is all you need to stay “competitive” to play top games. Maybe new SSD too. I don’t know how usual it is to upgrade parts along the way, not all at once. Especially in times like these just upgrading certain parts at a time is the only option for most.
