I would look at GB10 first if you want a simple single-machine setup with room for context and cache.
A 5090 can also be excellent if your chosen quantization fits inside 32 GB. That can give you much higher raw inference speed.
For Qwen3.8 27B specifically, AxForge already runs an NVFP4 version on GB10-class hardware. If you want dedicated hardware and simplicity, GB10 is the safe starting point; if speed matters more and the build fits, test a 5090.
