I'm currently running an i7-10700K, 32GB of DDR4, and an RTX 3070. Most games run well, but titles such as Jedi Survivor and Ratchet & Clank: Rift Apart don't look or perform as well as I'd like. Since upgrading the CPU would also mean replacing the motherboard and memory, I'm hesitant to spend money on a new DDR5 platform right now. My monitor is 1440p at 144Hz. Would pairing an RX 9070 XT with the 10700K be a sensible upgrade, or would the CPU hold it back enough that I should just replace the whole system?

You can keep the current CPU and RAM for now and move to a 5070-class card or better. Several people are getting excellent 1440p results with older six- and eight-core processors, particularly when using upscaling or frame generation. A newer CPU may improve high-refresh-rate minimums, but it isn’t automatically necessary for good 1440p performance.
You could also look at a later Intel processor paired with a DDR4-compatible motherboard, which would let you keep your existing memory. That may be worthwhile if you find a good deal on the used market, but I’d still start with the graphics card. The 10700K and 32GB of RAM are not obsolete, and a 9070 XT should provide a noticeable improvement at 1440p.
At 1440p, the graphics card will usually be the limiting factor, especially at high settings. A 9070 XT should be a strong upgrade from the 3070, and your 10700K is still capable enough that it shouldn’t make the purchase a waste. Upgrade the GPU first, then check your actual frame rates and CPU utilization before deciding whether the rest of the platform needs replacing.
If your main goal is maximum FPS and better CPU-limited performance, an X3D Ryzen chip would be a substantial step up. The 5800X3D can reuse DDR4, but it requires an AM4 motherboard, so it isn’t a drop-in upgrade for an Intel system and would still involve buying a board. It’s a reasonable used-market option, though a newer platform may make more sense if you want a longer upgrade path.
The 9070 XT is probably about as far as I’d go without changing the platform, but it makes sense for this system. Moving to DDR5 would add the cost of a motherboard and memory without necessarily giving you a dramatic improvement in every game. Take the upgrade one part at a time and see whether the GPU solves the problem.
I’m using an 11600K with a much faster graphics card and still run modern games at maximum settings. At higher resolutions, the CPU often matters less than people expect unless you’re specifically chasing very high frame rates.
