I'm putting together a system with a Ryzen 7 9800X3D, an Asus ROG STRIX B850-A GAMING WIFI motherboard, 16GB of TEAMGROUP T-Force Delta RGB DDR5-6000 CL38 memory, an MSI GeForce RTX 5070 Ti 16GB graphics card, and a 360mm liquid cooler. The oversized radiator is intentional, and I already have the case, power supply, and peripherals covered. I'm mainly wondering whether the 16GB memory kit is a bottleneck, since I'll be playing Counter-Strike and streaming at the same time. Would it be better to use 32GB or faster-timed RAM?

The RAM is only a bottleneck if you actually run out of it, but streaming makes that more likely. If memory usage reaches the limit, Windows will start relying on the storage drive, which can cause stutters and inconsistent frame times. For this build, 32GB is a sensible baseline rather than an unnecessary luxury.
For gaming and streaming, 32GB is the better choice. Sixteen gigabytes can still work, but the game, streaming software, browser tabs, Discord, and other background programs can push you close to the limit. A 2x16GB DDR5-6000 kit would give you more headroom without needing to add another kit later.
I’d choose DDR5-6000 CL30 if the price difference is reasonable. The speed improvement over CL38 won’t be dramatic, but it’s a nicer match for a Ryzen X3D system. Use two sticks rather than one, since dual-channel memory provides better performance and stability.
A Radeon RX 9070 XT may offer strong value compared with the RTX 5070 Ti, and the money saved could go toward 32GB of RAM. However, the Nvidia card has advantages such as its feature set and streaming-related capabilities, so the better GPU depends on whether you care more about price-to-performance or Nvidia-specific features.
The two cards aren’t identical, especially when features such as upscaling, ray tracing, and encoding are considered. I’d compare the current prices and decide based on the games and streaming tools you actually use.
Adding four sticks on AM5 can make memory overclocking or running at the advertised speed more difficult, so buying 2x16GB from the start is usually the cleaner option.
