My 13-year-old son is looking to build an AMD-based PC using the AM3+ platform because he prefers it over Intel due to concerns about IME and the vulnerability of UEFI BIOS. He is looking to buy some used pc components, I will handle the transactions for him. While he doesn’t have much money, he earns some by helping out with household chores, tuning up our piano, and training our GSDs. He’s aiming for a 990FX chipset motherboard and 32GB of DDR3 RAM (1600MHz or higher). For the GPU, he wants the AMD R9 390X or Vega 56/64. On the Nvidia side, anything better than a GTX 980 4GB will work. For the PSU, he wants something from the 80+ Gold rating and A/B tier list to ensure it lasts and doesn’t need replacing soon.
