5 things I wish I knew before spending extra money on faster RAM
Sometimes faster isn't actually faster.

It's easy to get wrapped up in the specs of a new PC build, so much so that you can lose sight of what's important -- your performance. One area that's especially true is memory speed, where faster DIMMs can represent a costly upgrade. Faster memory has its place, but if you aren't careful, you might spend extra money without any performance benefit.
