I am GPU poor and have a piece of crap rx570 8GB but still get ok performance out of qwen3.5-9B-4bit and various fine tuned versions. Plan on finally buying a decent gpu like a amd 7900 xtx. I still use claude for coding primarily but do research locally. What everyone has said about qwen3.8 though is making me feel I really need to invest in a decent rig.
