The user wants to know if this upgrade would enable them to run large language models like Deepseek V4.1 and GLM 5.3 Flash at lower quantization levels with improved performance, potentially surpassing models like Qwen 3.8 Flash Next. They are also considering a switch to DDR5 RAM if it offers a better solution. AI
