I'm considering spending around $400–500 on a Ryzen 7 5800X3D and a compatible motherboard. I could keep using my current DDR4 memory, which seems cheaper than moving to DDR5. My graphics card is an RX 6750 XT, and I mainly play at 1440p, especially Escape from Tarkov. Would the 5800X3D provide a meaningful enough improvement to justify the cost, or would another CPU/platform upgrade make more sense?

For Tarkov specifically, the extra 3D cache may help, so the 5800X3D could produce a noticeable improvement in some areas. However, the RX 6750 XT at 1440p will still limit performance in many games, so don’t expect every title to show a huge difference. It would also be worth moving from 16GB to 32GB of RAM if you stay with DDR4.
The 5800X3D can be excellent in games that benefit from extra cache, but $400–500 is a lot for an older AM4 platform. If you have access to a good bundle, an AM5 setup with a Ryzen 5 7500X3D or similar may cost about the same after adding memory and gives you a better future upgrade path.
Since you already have an LGA1700 motherboard, check its CPU support list and consider upgrading to something like a 12600K, 12700K, 13600K, or 14600K instead. Those chips can match or beat the 5800X3D in many games and may only require buying the CPU. Update the BIOS before installing a 13th- or 14th-generation processor.
The 5800X3D is effectively the top gaming upgrade for AM4, so it doesn’t really provide a future CPU path beyond that platform. Its advantage is keeping inexpensive DDR4, not future expandability. Compare actual Tarkov benchmarks before buying, because the best choice depends heavily on your current motherboard, RAM speed, and target frame rate.
I’d avoid spending that much on the 5800X3D unless you find it and the motherboard at a particularly good price. A Ryzen 5 7600X or another affordable AM5 CPU with a reasonably priced board and DDR5 can be a better long-term purchase, while a discounted LGA1700 CPU is likely the cheapest immediate upgrade.

That makes sense. I was mainly looking at the 5800X3D to avoid replacing my memory, but I’ll compare it with a cheaper LGA1700 CPU and an entry-level AM5 build before deciding.
