What to look for in motherboards

Match the chipset to actual feature use: X870E enables dual PCIe 5.0 x8 GPU + Gen5 NVMe; X870 is single-GPU + 5.0 NVMe; B850 saves $80 vs X870 for builders who don't need overclocking or USB 4. VRM matters at the top of the CPU stack: a Ryzen 9 9950X3D will throttle on a budget A620 board's 8-phase VRM under all-core load. USB 4 / 40 Gbps is genuinely useful (single-cable docks, external GPUs); USB 20 Gbps Type-C front-panel headers also matter — 50% of "premium" Z890 boards still ship only 10 Gbps. Avoid: any motherboard with only 2.5 GbE LAN if you have a 10 GbE switch, ITX boards with single M.2 (storage upgrade path is dead), and Wi-Fi 6 boards in 2026 — Wi-Fi 7 is the new floor.
