I have a couple of Supermicro boxes that are 4/8 way Xeons.

1. Yes, you can run Windows.
2. Large memory allocation is transparent and far-side NUMA latency is not significant.
3. Most chess engines doesn't spread threads properly across Processor Groups when you have more than 64 cores, including SF.
4. You will almost always want more cores, <= 1TB memory usage of Xiangqi EGTBs takes about 3 years to build on 4x4669v4 running 24/7.
5. HT gives about 30% overall NPS increase but can cause ELO drop due to poor performance on logical cores.
