16GB is enough for gaming.

No, you won’t see a difference if the game uses less than 16GB. More RAM doesn’t make a game faster once you have enough—it just sits there unused.

Dual-channel bandwidth is the same with two 8GB sticks as with two 16GB sticks. The extra capacity only helps if you’re running a bunch of background apps (browser tabs, Discord, streaming) that push total usage over 16GB. If you just game and close everything else, you’re fine.

The real gotcha is that some modern games do creep over 16GB when you factor in Windows overhead—especially open-world titles or poorly optimized ports. But for the average game today, 16GB dual-channel is the sweet spot. 32GB is future-proofing or for people who also edit video.

Save your money. A faster GPU or CPU will make a much bigger difference.
