First Time PC Build Help!

Hey everyone! So basically I am researching how to build my first gaming PC. I have posted on another forum and have gotten excellent service from some people referring parts. I wanted to re-post these parts here and see what you all think. The total for everything (minus case, monitor, etc.) is approx. $1045.00! What type of games and what settings do you think I could get using this build? Any recommendations? Here is the list:
