Do I need 32GB of RAM for modded games like Sims 4 or Skyrim?

Yes, if you’re running heavy mod lists. Mods eat RAM — high-res textures, script-heavy mods, and custom assets pile up fast. 32GB prevents stuttering when your system would otherwise start swapping to disk. 16GB is still fine for lightly modded games, but if you’re installing 200 mods and expecting smooth 60fps, 32GB gives you the headroom to avoid hitting the page file.
