I've built one PC before and want to upgrade my current system for my daughter while assembling a new gaming PC for myself. My current system has a Ryzen 5 3600, RTX 3070, Gigabyte B550 AORUS ELITE AX V2 motherboard, 32GB DDR4-3600, a 1TB NVMe SSD, and a 2TB hard drive. I'm considering replacing only the CPU, although I'm not sure whether an upgrade is necessary yet. The B550 platform should support newer Ryzen 5000 processors with a BIOS update.
For my new build, I'm aiming to spend around $2,000 USD, but I want to avoid wasting money on parts that won't improve gaming performance. My draft includes a Ryzen 7 9700X, 32GB DDR5-6000, an X870 motherboard, a 4TB NVMe SSD, an RX 9070 XT, a 750W power supply, and a 1440p 180Hz monitor. Are there any parts I should change, and what would be the most sensible upgrade path for my daughter's PC?

If you do want to upgrade the existing machine now, look at the Ryzen 7 5700X3D rather than paying a premium for an older 5800X3D. It gives the AM4 system a substantial gaming boost and should work with the B550 board after updating its BIOS. Check the motherboard’s support list and update the BIOS before swapping CPUs if required.
Don’t overlook what your daughter actually plays. For Minecraft and other lighter games, the existing hardware is more than enough, and a fun case, lighting, monitor, or additional SSD may matter more to her than a CPU upgrade. You can always move to a 5700X3D later if the 3600 starts limiting performance.
For the new build, prioritize the graphics card because it has the biggest effect on gaming performance. The Ryzen 7 9700X is already more than capable, so you could save money on the motherboard, cooling, and storage instead of overspending on an X870 board or an especially expensive SSD. DDR5-6000 is a sensible target, but make sure the memory price is realistic—$500 for 32GB is far too high. A good air cooler would also be sufficient for the 9700X unless you specifically want an all-in-one cooler for appearance.
The current system is already well balanced for 1080p or 1440p gaming, so I wouldn’t rush to replace the CPU for your daughter. A 3600 paired with an RTX 3070 should handle lighter games very well. If she eventually needs more CPU performance, a Ryzen 7 5700X3D would be a strong drop-in upgrade after a BIOS update. Expanding the storage may be more useful than replacing the processor immediately.
