Those are very memory non-intensive applications, so you almost definitely wouldn’t notice a difference.

The reason it’s better for gaming is that games need to load big textures and models into ram to show new content, and that can cause lag when the ram is too slow. Since you’re gaming, you’ll notice the lag.

While watching a video, the video is buffered into ram much faster than you can watch it, so there won’t be any difference.

While browsing, pages might take around 10 to 50 ms longer to load, but you’re not going to notice that. Most pages load bits and pieces when you click around anyway, so there will be negligible difference after the initial page load.
