This would be my first PC build, and I have a fairly flexible budget. I want a system that can handle demanding games at high settings while also supporting streaming, recording, video production, development work, and several heavy applications running in the background. The planned parts are a PNY GeForce RTX 5070 Slim, WD Black SN7100 2TB PCIe 4.0 NVMe SSD, 32GB DDR5-5600 memory, a Thermalright Levita Vision 360mm liquid cooler, AMD Ryzen 9 7900X, Gigabyte B650 UD AX motherboard, and a Phanteks XT View Matrix ATX case. I am also considering an ASUS TUF Gaming 1000W 80+ Gold ATX 3.1 modular power supply. Is this combination compatible and well balanced, or should I change any parts for better gaming and content-creation performance?

The parts should generally be compatible: the B650 board supports the AM5 processor and DDR5, and the case supports an ATX motherboard. However, DDR5-5600 is a little conservative for Ryzen. A reputable 32GB or 64GB DDR5-6000 EXPO kit with reasonable timings would usually be a better choice. I would also verify that the 360mm radiator fits in the case in the exact position you plan to use, and check the motherboard BIOS version before installing the CPU.
For streaming and recording, the RTX 5070's hardware video encoders can handle much of the workload, so you do not necessarily need an extremely high-core-count processor. Make sure you add enough storage if you plan to keep lots of recordings, and consider 64GB of RAM if your editing projects or background applications are particularly demanding. The included case fans and the CPU cooler's airflow setup are also worth checking so the radiator and graphics card receive adequate ventilation.
A quality 1000W ATX 3.1 supply is more than enough for an RTX 5070 system and leaves plenty of upgrade headroom, though you could likely use a good 750W or 850W model and spend the difference elsewhere. Also compare the RTX 5070 with similarly priced competing cards before buying; Nvidia may be preferable for streaming software, ray tracing, or applications that benefit from CUDA, while another card could offer more raw performance or VRAM for the money.
The 7900X makes sense if you regularly render, edit, compile, stream, or multitask, but it is more CPU than you need for gaming alone. For a gaming-focused build, a cheaper Ryzen 7 chip could free up money for a faster graphics card or a better memory kit. If gaming and production are equally important, the 7900X is still a reasonable middle ground.
I am mainly aiming for gaming plus streaming, recording, development, and content creation, so I do want enough cores for heavy background tasks rather than building only for games.
