I don't have 5090, I have 395+ and I use for gpu assisted OCR, embeddings vector, speach to text and etc. I have a freedom of using a large library of various models and I can fit a lot in 128gb.
I don't use it for coding, I have $20 Gemini, $20 codex, etc.
But then I got the framework board for $1700, now it's $2700
