My current system has an Intel i7-6700K, 32GB of DDR4 memory, and an RTX 4060. After nearly ten years, I want to replace the processor, but current memory prices make the decision harder. I could choose a DDR4-compatible platform such as AM4 or LGA1700 and keep my existing RAM, which would be cheaper but leave me on an older ecosystem. Alternatively, I could move to AM5 with DDR5 for a higher upfront cost and a longer upgrade path. In my area, 32GB of DDR5 costs around €500, which is roughly comparable to the price of a Core i5-14400, motherboard, and cooler. Which option makes the most sense for gaming and long-term value?

If keeping costs down is the priority, AM4 is still a very practical upgrade. A Ryzen 5 5600 paired with a B550 board would be a huge improvement over the i7-6700K, and you could continue using your current DDR4 kit. A higher-end AM4 chip only makes sense if you find it at a good price; expensive top-end parts can bring the total close to an AM5 build.
Avoid paying an inflated price for a high-end AM4 processor. If a Ryzen 7 5800X3D or similar chip costs nearly as much as a newer platform, AM5 is the better long-term purchase. For the lowest total cost, a Ryzen 5 5600-class build is sensible; for longevity, choose AM5 and accept the higher upfront memory cost.
You do not necessarily need to replace your DDR4 just because you upgrade the CPU. The i7-6700K officially supports slower DDR4, but your existing 32GB kit can still be reused with a compatible newer motherboard. Check its speed and condition, then include new memory in the budget only if you move to AM5 or your current kit is unusually slow.
I would lean toward AM5 if you can afford the initial cost. Your current processor is old enough that replacing the platform is justified, and AM5 gives you a better chance of upgrading the CPU later without replacing the motherboard and memory again. Pairing a midrange processor with 32GB of DDR5-6000 is plenty for an RTX 4060 system.
LGA1700 is another middle-ground option because some boards support DDR4 while others support DDR5. A Core i5-14400 with a DDR4 motherboard could let you reuse your existing memory, though the platform has less future upgrade potential than AM5. It may still be the best value if those parts are substantially cheaper where you live.
A Ryzen 5 5500X3D with a B450 or B550 board could also be worth considering if gaming performance is the main goal and you find one around the same price as a basic upgrade.
