I rarely upgrade my computer—my current CPU and motherboard are nearly 10 years old—so I want this build to last and remain reasonably upgradeable. I mainly browse, game, and do some video editing. I already have an RX 6600 that I plan to reuse, since I mostly play single-player and indie games, but I would like the option to play future AAA titles at reduced settings. Smooth 1% lows matter more to me than maximum graphics quality.
My main options are an AM5 DDR5 system with a Ryzen 5 9600X, MSI MAG B850M Mortar, and 16GB of Kingston DDR5-6000 CL36 memory; an Intel DDR4 system with an i5-14600K, a B760 DDR4 motherboard, and 32GB of DDR4-3600; or an AM4 system with a Ryzen 7 5700X, B550 motherboard, and 32GB of DDR4-3600. The DDR5 memory costs significantly more while offering only 16GB, but AM5 would provide a much better future CPU upgrade path. I am also concerned about the long-term reliability and upgrade limitations of Intel's 13th- and 14th-generation platform.
The rest of the build would use a Thermalright Phantom Spirit 120 cooler, Thermaltake View 170 case, Corsair RM750x Shift power supply, Kingston KC3000 SSD, and my existing RX 6600. Since I keep systems for a long time, should I accept the higher memory cost and start with DDR5/AM5, or save money with DDR4 and prioritize having 32GB immediately?

The decision ultimately depends on your budget, but the DDR4 savings do not look large enough to justify starting a new long-term build on an older platform. AM4 and Intel DDR4 can still perform well today, but neither gives you much of a future CPU upgrade route. If you can afford AM5 without sacrificing more important parts, it is the safer long-term investment.
DDR4 was a sensible choice a few years ago when DDR5 was expensive and immature. Today, the performance difference is not always dramatic, but the platform longevity matters more than the memory standard itself. AMD’s AM5 ecosystem offers the clearest route to a future CPU upgrade, whereas the Intel and AM4 choices are mostly buying into hardware that has already reached its endpoint.
A DDR4 system is still perfectly usable, especially with 32GB and an RX 6600, but it makes more sense when the budget cannot stretch to AM5. For a fresh build that you plan to keep for close to a decade, I would avoid both AM4 and Intel’s older DDR4 platform. Just keep in mind that 16GB may become limiting sooner, so upgrading to 32GB should be part of the AM5 plan.
AM5 is the strongest choice from these options. It gives you a current platform with a realistic path to drop in a faster CPU later, while both DDR4 platforms are effectively end-of-line. Since you tend to keep systems for many years, that upgrade flexibility is probably worth more than the initial memory savings.
That makes sense. I would prefer not to spend so much on less memory, but longevity is the priority, so I will probably choose AM5 and upgrade the RAM later if prices improve.
