People often don’t realize that a PCs are built for a certain purpose. When it comes to the focus of a PC build, the items you tweak are always the graphics, CPU, storage, and memory. For example, a person who needs a PC for audio/video editing will need much more RAM than someone who is building gaming system. If you need more than the now standard 4 GB of RAM, then the G.Skill Ripjaws X DDR3 2133 MHz RAM may just be what you need and they come with a massive frequency boost over the run of the mill 1333 or 1600MHz modules.
