16GB is non-negotiable for that build.

Yes, you’ll see a noticeable jump, often well over 10% in many modern titles.

With an RTX 3060 and Ryzen 5 5600X, 8GB of RAM is the bottleneck—period. Games like Call of Duty, Cyberpunk 2077, or Starfield will stutter and drop frames because the system is constantly swapping data to your SSD. Dual-channel 16GB gives the CPU enough breathing room to feed the GPU properly.

The 10% number is conservative. In heavy open-world games, you might see 20–30% improvements in 1% lows, which is what actually makes the game feel smooth. 8GB is a waste of that processor and graphics card.

Don’t skimp on RAM for that setup.
