GeeCoolThe 7600 runs on AM5 with DDR5. B650 is the balance of expansion and price; A620 fits a tight stock-power build with one GPU and one M.2; B650E/X670E only for more PCIe 5.0.
Verify BIOS and the memory QVL. Gaming prioritizes the GPU and M.2; sustained compiling/rendering justifies more VRM cooling. The 7600 has an iGPU but it's not a dGPU replacement — the motherboard's display outputs only matter if you're using the iGPU.
