First build on a $700-800 budget

[trick069]

Getting straight to it, I need advice on the parts i've picked for my first build. I'm working with a $700-800 budget, i need to include a monitor, and i don't need an os, keyboard, or mouse. I plan to use it for gaming, multi-tasking, and watching movies. I made a list on pcpartpicker but i'm not sure if I will be getting my moneys worth from the parts i've chosen (i.e. is my cpu overkill for this setup? is there a better gpu at the same price?). I'm sure there's a sticky somewhere that i missed on how to post a list from pcpartpicker but this is my best shot:

Aslo, i'd like to keep the same case and keep it an intel based cpu.

Thanks for any help in advance.
