Upgrading from 1xR9700 to 2xR9700. Thoughts on build before buying?

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.
