Setup advice. New RTX 5090 32gb ram + 96gb Ddr5 ram.

I was playing with different models but not quite what I'm after. I want to be able to run Kimi 2.5 for coding similar like Opus locally. Specifically I want to replace CodeX on my device. Running other models I had issues with tools using Goose. Even asking a smaller model to review projects in a folder wasnt working like I wanted. In addition I wanted something to handle comfyui prompts and workflows on the device. I can buy another 96gb ram if needed. I still have 2 slots open.
