My first built computer ( help! )

[Drakomon322]

Hey guys, this is my second post in this forum. In the first one, I recieve a lot of feedback from good people, which I really appreciate. I made some changes to my pre built.  I would like to know what you think about  it and if it is necessary to change or add more parts.

My budget is between $800 USD  and $900USD , but it would be nice to reduce it to 800$ USD or less ( if it is possible)

Thanks 

P.D

- I already have a mic,a keyboard, a mouse, a keyboard, a monitor and an optical drive.

- I am majoring in software engineer and I love playing videogames ( Dota 2, CS GO, Hearthstone, Starcraft 2 , HOTS, Mortal Kombat X and more on) so i am gonna use this computer for engineer stuff and gaming.

- I am going to overlock the computer, but I dont know if the PSU is the right choice for it. Please, let me know, so I can change it
