从 1xR9700 升级到 2xR9700：购买前求配置建议
Upgrading from 1xR9700 to 2xR9700. Thoughts on build before buying?
一位用户计划在现有 R9700 单卡（64GB RAM）基础上加装第二张 ASRock Creator Radeon AI PRO R9700 32GB 显卡，以提升速度并运行 Qwen3.8-Flash-Next 的 Q4 及更高量化版本（3.8 27B）。他已选用支持 x8/x8 拆分的技嘉 B850 AI TOP 主板，整套配置总价约 6307.84 美元，正征求购买其余配件前的改进意见。
Currently have a R9700 build with 64GB RAM. Want to get a second one for both speed and the ability to run Qwen3.8-Flash-Next at Q4/higher quants of 3.8 27B. Looking for thoughts or any improvements before buying the rest of the parts.
Made sure to get a motherboard that supports x8/x8 bifurcation. Some prices, like the RAM, are very cheap as I bought them two years ago and I'm upgrading from a previous build.
