Suggestions & Opinions on My First Gaming PC Build

I have built this computer for mostly gaming in mind. I would like to play most games on at least medium, and my budget is around $900-$1000. I also have no plan on overclocking.

Cheaper and better than your build. This will run games on Ultra with 55+ FPS.

Thanks for that. I originally wanted to go with Intel, but this build has made me switch my rig.

Intel is best for higher end builds. Definately go with AMD for budget builds.
