I built this gaming PC in 2020 and would like to keep using it for as long as possible. How long should it remain capable of running modern games at 1080p, ideally at 60 FPS or higher with high settings? I upgraded to 32GB of RAM last year and replaced my old graphics card with a GIGABYTE AMD RX 9060 XT 16GB yesterday. The rest of the system is an Intel Core i5-10600K, 32GB DDR4-3600 memory, an MSI Z490 Gaming Plus motherboard, and a 550W Xilence XN045 power supply.

There is no single expiration date for a PC. If you are happy with the performance, it is still doing its job. Older midrange cards can remain useful for many years, especially for a large library of existing games, multiplayer titles, and well-optimized releases. New blockbuster games may occasionally require compromises, but that does not make the whole machine obsolete. Based on your target, I would expect it to stay useful for roughly four to six years, with some settings adjustment toward the end.
Your graphics card should be comfortable at 1080p, and 32GB of RAM is plenty for current games. The power supply is the component I would investigate most closely—not simply because it is 550W, but because the exact model, age, quality, and protections matter. The wattage may be adequate for this GPU, but a future upgrade would be a good opportunity to install a well-reviewed unit. When you eventually need a major platform upgrade, it will probably make more sense to replace the CPU, motherboard, and RAM together rather than buying a high-end processor for the older socket.
For 1080p gaming at 60 FPS, this should probably serve you well for another three to five years. The RX 9060 XT’s 16GB of VRAM is a strong point, and you already have enough system memory. The i5-10600K will be the part most likely to hold you back, especially in CPU-heavy games or if you want 120–165 FPS, but there is no reason to replace it until you actually notice a problem. You may eventually need FSR or slightly reduced settings in demanding releases.
The system will remain usable for quite a while, but the exact answer depends on what you play and what you consider high settings. In two or three years it might no longer maintain 60 FPS in every demanding game without turning down a few options. Modern upscaling technologies such as FSR can extend the useful life of the graphics card considerably, and many games will still run very well after you stop using maximum settings.

That was my reasoning for choosing the 16GB 9060 XT. It is a big step up from my RTX 2060 Super while keeping power usage close enough that I could continue using my current PSU for now. I may replace the PSU with a newer, reputable model later for peace of mind.
