Does adding more RAM actually make your computer feel faster?

Yes, adding RAM makes your system feel snappier because it reduces how often Windows has to swap data to the page file on your disk. RAM is like desk space; the page file is a filing cabinet across the room. Every time the system pages data in or out, you feel that wait as a stutter or lag. More RAM keeps everything in memory, eliminating that bottleneck. If you’re at 8GB and often at 90%+ usage, jumping to 16GB will make a bigger difference than a faster processor.
