Hello, As I am getting into my first custom build (potentially) I am learning that I know far less about this stuff than I thought I did. Does anyone have a site(s) that could help me learn what all of the numbers mean and compare similar components. For example, I can see that a 1080 gpu at 3.8 mhz is better than a 1070 gpu at 3.6mhz. But I don't know how much better it is, what the limitations of each are, or what exactly the 3.8mhz means (This sort of confusion applies to many of the various components of the computers. Thanks for any input in advance.
