GeeCoolThe 8600G runs AM5 with DDR5. For an iGPU-only budget build, A620 is enough; step to B650 for more USB, M.2, and VRM margin; B650E/X670E matter only for more PCIe 5.0.
Verify BIOS and the memory QVL. iGPU gaming prioritizes dual-channel bandwidth; sustained compiling or rendering justifies stronger VRM cooling. Keep board spend in check and put the budget into memory.
