Best build for 800 dollars??

Hi. i need a build for my friend. something that will play Arma/dayz and some future games like RE6. Dont need KB/M or monitor. thanks!

I've not done this in awhile, so please feel free to correct/tweak GSers. This is what I would do though if I had to make a $800 build.

Here's an idea without OS

FX 6100

Mobo

8gb DDR3

Case

PSU

1Tb Hdd

7870 ghz
