Hardware ideas should I get a New motherboard and CPU?

I am looking at changing my server to a new motherboard and cpu.

what do people think about these 2?

ASUS Pro WS TRX50-SAGE WIFI CEB Workstation motherboard, AMD Ryzen Threadripper PRO 7000 WX,ECC R-DIMM DDR5, 36 power-stage, WiFi 7,PCIe 5.0 x 16,PCIe 5.0 M.2, 10 Gb and 2.5 Gb LAN, multi-GPU support.

and

AMD Ryzen™ Threadripper™ 7960X 24-Core, 48-Thread Processor

Hard to answer without any context re: use case.

For example, if this is a file server-only application then this CPU is likely nuts. So, what is your use case and what about the hardware you want to use for the pool?

Good point — this won’t be just a file server. My HL15 (TrueNAS CE) already handles the main ZFS pools, but I’m building this system for mixed workloads: VM hosting, Docker stacks (Tdarr, Immich, Nextcloud, etc.), and GPU-accelerated transcoding.

I also want to expand storage with several 4 TB NVMe drives for high-speed pools and caching — and most boards choke on lanes before you can really scale that. The TRX50-SAGE gives me the PCIe 5.0 slots and ECC DDR5 support to keep everything running at full bandwidth. Basically, I’m aiming for a workstation-class NAS that can double as a compute and AI node without hitting I/O limits.
