I ran a 10-minute Cinebench multi-core test on my PC with a Ryzen 7 5800X3D, Radeon RX 9070 XT 16GB, 32GB of DDR4 memory, and a DeepCool LM360 AIO cooler. The CPU reached a maximum of 77°C, and the score was roughly in line with typical results for this processor. Is that a good temperature? Since Cinebench puts the CPU under a sustained heavy load, can I assume gaming temperatures will stay below 77°C as well?

Gaming temperatures will probably stay below that, but it is not guaranteed. A game can heat the CPU and GPU at the same time, and the GPU may raise the temperature inside the case. Shader compilation or especially CPU-heavy games could also create brief spikes.
Cinebench is a useful real-world estimate, but some stress tests can draw even more power and produce higher temperatures. If you want to check the absolute worst case, try a heavier CPU stress test or run a CPU and GPU test together. For everyday use, though, 77°C is nothing to worry about.
Yes, 77°C after a full sustained multi-core run is a very good result for this processor. Cinebench is usually more demanding than normal gaming, so most games should run cooler, especially if they do not fully load every CPU core.
