GeeCoolThe 265F sits on LGA1851 with 800-series chipsets and is DDR5-only, unlike the LGA1700 era where you could pick DDR4 or DDR5.
A B860 board is plenty for a gaming build; Z890 mainly buys extra M.2/PCIe lanes and tuning features. Before buying, confirm the BIOS supports the CPU, check the memory QVL, and see whether the GPU slot shares lanes with M.2 slots.
