Why does everyone say RAM speed doesnt matter? everyone say its only 1fps differ and doesnt matter in gaming in every forum i visit, and i believed that for a long time but i found those video by digitalfoundry that show a significant different of often 8fps or more. and i found benchmark around the web that give similar result.

Well, I prefer to claim price/performance ratio is getting pretty poor above 3000MHz (DDR4, Skylake/Kabylake)...

It's always matter of use case...

To go absurd, if your code and data fits in CPU cache, it wouldn't matter whether your RAM is 10MHz or 10GHz.

Once you get RAM heavy application and don't have bottleneck elsewhere, you'll see significant improvement due to increased RAM bandwidth.

In general the returns in high RAM speed are not significant enough to force it in general use case, but that doesn't mean you can't find one where it will be worth the extra money for you.

It matters of course if the extra FPS allow you a better gaming experience. Often, a few extra FPS gives no perceivable difference in the experience.
