I'm mainly going to be streaming League of Legends, playing it a lot of course. Don't have a lot of money, but still wanting to get my moneys worth. Not looking to spend over $800-850. My friend put this all together, i'm not good with all this. He will help me build it.

Overclocking does very little for gaming. This configuration is built instead to save money.
