My i7-8700K has been causing noticeable CPU bottlenecks, and I'd like to improve performance without rebuilding the entire PC. My current system has an MSI Z390M motherboard, 32GB of G.Skill DDR4, an RTX 3080 Ti, and a Corsair H100i-style AIO cooler. I'm considering replacing only the motherboard and CPU while keeping my DDR4 memory, graphics card, storage, and possibly the cooler. What upgrade path offers the best value, and would my current AIO be compatible with a newer socket?

Before upgrading, confirm that the CPU is really the limitation. The result depends heavily on which games you play, your resolution, refresh rate, and settings. Monitor CPU and GPU utilization and temperatures while gaming. If the processor is maxed out while the 3080 Ti is underused, an upgrade makes sense; otherwise, thermal throttling or a settings issue could be the real cause.
A used Core i5-14600 with a compatible motherboard can be competitive with the faster Ryzen gaming chips and may be cheaper as a bundle. Make sure the board has adequate VRM cooling and that the BIOS supports the processor. Also check whether your AIO has the correct LGA1700 mounting hardware; older Corsair kits may require an adapter bracket.
DDR4-compatible platforms are still the sensible choice if you’re trying to control the cost. Moving to DDR5 would add the price of new memory on top of the CPU and motherboard, without necessarily giving you the best value for this upgrade. A used 12th-, 13th-, or 14th-generation Intel CPU and motherboard bundle could also be worth considering, especially something around the Core i5-12600K or better. Just verify the motherboard quality and CPU model before buying used.
A Ryzen 5 5600X3D or 5700X3D paired with a decent B550 board is a strong budget-friendly option if you want to keep using DDR4. The 5700X3D is especially attractive for gaming and CPU-heavy titles, while a 5800X3D-class chip can make sense if you also need extra cores for work or streaming. You may need a mounting bracket for the Corsair cooler, so check the exact H100i model and whether it includes AM4 hardware. Otherwise, a basic Thermalright air cooler is inexpensive and simple.
It’s generally straightforward. You’ll need a fresh motherboard, should update or reinstall drivers, and a clean Windows installation is recommended for the smoothest transition. Your GPU, memory, and other components can carry over.
Would switching from Intel to AMD cause any major issues? I’ve only used Intel platforms before.
