Building first gaming desktop, need assistance

[macdaddyslacks]

Hey there, i recently decided i want to build my own gaming desktop after my laptop died out on me and i have a few questions. I've done a little research and put together this build that has a SSD for the OS and some games:

Some of my concerns are

• 
  Do i have all the parts i need?
  Are there things there that i don't need?
  Is everything compatible (how/what do i do to check if they are)?
  Are any of those parts shotty or not recommended?
  And Ultimately, will it work?

I've asked some friends of mine but most of them are less experienced than i am so any help would be greatly appreciated. Thanks

Increased the budget by $20 for MUCH better performance.

Everything in this is compatible in stock and will get the full potential of this build.
