<ol>
<li><strong>魔改卡本身的长期风险</strong>（跟显存容量无关）：</li>
</ol>
<ul>
<li>非官方方案：拆原装散热、后加显存，颗粒体质/虚焊是长期隐患，满载 320W 跑几个月后出问题的案例论坛里见过</li>
<li>保修 = 卖家个人承诺，个人店说没就没，跑了没售后；你楼上 Takano RR 那家算做得久的，但风险性质不变</li>
<li>带宽要问清：32G 魔改方案各家不同，有的换 GDDR6，带宽比原版 736GB/s 低一截。跑 LLM 影响不大（27B 吃容量），跑游戏/ComfyUI 出图有差</li>
</ul>
<ol start="2">
<li>
<p dir="auto"><strong>性价比锚点变了</strong>：现在原生 32G 的 R9700 就在同一价位段。原生显存 + 官方保修更省心；除非你离不开 CUDA 生态（ComfyUI 插件/音频/某些框架），否则同价位选 R9700 是论坛主流结论。</p>
</li>
<li>
<p dir="auto"><strong>双卡 64G 跑 27B</strong>：完全够。Qwen3.8-27B FP8 权重约 54.6G，剩约 9G 给 KV（够 40-60K 上下文，开 KV 量化更多）。tensor-split 双卡，PCIe x8+x8 就行不需要 NVLink（27B 小，PCIe 不是瓶颈），速度参考论坛双卡数据：双 16G 卡 Q4 已到约 50 t/s，你双 32G FP8 大致 45-55 t/s——容量和上下文是双卡的意义，速度不会翻倍。ComfyUI 双卡吃满要按节点拆，单卡分时段更省心。</p>
</li>
</ol>
<p dir="auto">实操建议：<strong>先别急着买第二张</strong>。第一张满载跑 1-2 周（长上下文 + ComfyUI），确认无花屏/报错/虚焊迹象再入。魔改卡最怕"第一张没事第二张是雷"，双卡 = 风险翻倍。电源按两张 320W 算，850W 起步。</p>
