I'm planning a new PC build and am considering AMD's AM4 platform because the parts can be considerably cheaper, especially while DDR5 memory remains expensive. My main concern is future upgradeability: I'd like to upgrade the CPU or other components over time rather than replace the whole system. Is AM4 still reliable and capable in 2026, or would it be better to start with AM5 despite the higher upfront cost?

If this is a completely new build and your budget allows it, AM5 is the better long-term foundation. You pay more now, but you keep the option of upgrading the processor later without replacing the motherboard and RAM. That said, expensive DDR5 can change the calculation. Spending hundreds extra on memory just to choose AM5 may not be worthwhile if it forces you to buy a weaker GPU or cut back elsewhere.
For gaming, a high-end AM4 chip such as the 5700X3D or 5800X3D still performs very well, particularly at 1440p or 4K where the graphics card is often the main limitation. AM4 can be a very cost-effective choice if you find the CPU, motherboard, and DDR4 memory cheaply. It makes less sense if your priority is getting several future CPU upgrades from the same platform.
The decision mostly depends on your budget and performance target. AM4 can still handle modern gaming well, even with powerful graphics cards, but newer games may become increasingly CPU-heavy over time. If choosing AM5 only leaves you with a much weaker GPU, AM4 may provide the better experience today; if the price difference is manageable, AM5 avoids having to replace the CPU, motherboard, and RAM together later.
AM4 is still reliable and plenty capable, but its CPU upgrade path is effectively finished. The Ryzen 5000 lineup was the last major generation for the platform, so a Ryzen 5700X3D, 5800X3D, or 5950X is about as far as you can go. You can still upgrade the graphics card, storage, and memory, but a future CPU upgrade beyond that would require moving to a new motherboard and DDR5 memory.
AM4 is especially reasonable for a budget-conscious build or for upgrading an older system. A 5700X paired with an inexpensive board can deliver a major performance increase without spending AM5-level money. Just treat it as a mature, finished platform rather than an upgradeable one: buy the level of CPU you expect to keep for several years, then upgrade the GPU when needed.

That’s the part I’m worried about: if DDR5 becomes cheaper later, moving up from AM4 would mean replacing the motherboard, CPU, and memory instead of just swapping the processor.
