Looking for a gaming pc for a budget of $800

[Bangerdead]

So i'm a first timer pc builder and i'm looking to build a gaming pc for around $800.(saving some $$ for the OS and peripherals)I've done loads of research on gaming pcs and I think I've got a good idea on what to look for. Im hoping my PC will run games like bf3/bf4, far cry 3, dayz and rust at max or high settings at acceptable frame rates(40-60). So far i've found that this build will suit my needs:
AMD fx-6300
Hyper 212 EVO
Asus M5A97 R2.0
WD Blue 1tb 7200 rpm
G.SKILL Ripjaw 8 gb (2x4gb)
Asus R9 270
Corsair CX600 600w
Coolermaster HAF 912

I am curious to know if this build will be good enough for what I am intending to use it for. Are there any other parts i could consider for this build that would give similar or better performance within a range of 50$ over my budget? Any advice will help a lot since this is my first time.

Thanks a ton in advance

Thanks for the quick reply. How reliable are these parts, and would they be somewhat futureproof aswell?
