I'm trying to decide how to get the best gaming performance per dollar from my current system. My overclocked Ryzen 5 5600 seems to be limiting my RTX 5070 Ti, especially in average FPS and 1% lows at 1440p. The system has 32GB of DDR4-3400, an MSI B450 Tomahawk Max II, a 420mm custom AIO, and a 750W Gold-rated PSU.
My main option is a used Ryzen 7 5700X3D for about $350, which should drop into my existing AM4 platform. The alternative is a complete AM5 rebuild with a Ryzen 7 7800X3D, B650 motherboard, and 32GB of DDR5, costing roughly $1,150 or more. I've also considered a used Intel 13700K or 14900K with a DDR4 Z-series board, but the higher power draw, platform concerns, and possible PSU upgrade make that route less appealing.
A new 5800X3D costs around $500 locally, so it doesn't seem worthwhile. Would a 5700X3D noticeably improve average FPS and stuttering with the 5070 Ti, or is the 5600 still good enough for 1440p? Is AM5 worth the much higher price strictly for gaming, and are there better CPU or platform options I'm overlooking?

It would help to quantify the ‘massive’ FPS loss and brutal 1% lows first. If the GPU is already near full utilization, a CPU swap won’t transform the experience. In genuinely CPU-limited games, though, moving from the 5600 to an X3D chip should make a noticeable difference. One owner reported much smoother results after moving from a regular 5600 to a 5800X3D, particularly in demanding path-traced games.
The Ryzen 5 5600 is somewhat behind what you’d ideally pair with a 5070 Ti, but it shouldn’t normally cause catastrophic performance. Before replacing the CPU, check whether the DDR4-3400 setup has an appropriate FCLK and consider tuning the memory timings. That can help with frame-time consistency and 1% lows.
A 5700X3D would improve performance in CPU-limited games, but $350 is a pretty steep price for an AM4 upgrade. If your current games are already running well, the improvement may not justify that cost. AM5 makes more sense as a longer-term platform, but paying over $1,100 solely for gaming is difficult to justify unless you also want the upgrade path.
A 14600K with a suitable B760 board is another possibility and can compete with the 5800X3D in games while offering stronger multi-core performance. A 5500X3D is also worth checking if it’s significantly cheaper, since its gaming performance can be surprisingly close to the higher-end AM4 X3D chips.
