Console Gamer Moving On "HELP"

So hi everybody. So I have been watching tek syndicates youtube videos and i have also been looking through the forums as well and i dont know if im blind but i couldnt find the awenswer to my overall question. Now I do know a little bit about computers but not nearly enough to know how much performance is needed to play certain games. I am wanting to build a gaming pc for around 800-850$ that can run battlefield 3,4 and planetside 2 on at least better then console quality and FPS. I just need some advice for what type of processor to get and what graphics card is best. Please let me know if it is even possible on my budget and help me make a easy switch into the pc comunity . 

Thanks, Ian :))))))

CPU: AMD FX-8320 3.5GHz 8-Core Processor.  Will perform quite well, especially in BF4.  8 cores, and should perform close to an i5.

MoBo: Asus M5A99FX PRO R2.0 ATX AM3+ Motherboard.  A good motherboard the can handle the power hungry FX-8320

RAM: Crucial Ballistix Sport 8GB (2 x 4GB) DDR3-1600 Memory.  All you need for gaming in this day and age.

SSD: Kingston SSDNow V300 Series 120GB 2.5" Solid State Disk.  Put your OS and games on here.  Your computer will boot in seconds and programs will launch super fast :D.

HDD: Western Digital Caviar Blue 1TB 3.5" 7200RPM Internal Hard Drive.  Mass storage drive for everything else.

GPU: XFX Radeon HD 7970 3GB Video Card.  AMD's old high-end card.  They're being restickered as R9 280Xs, and are still pretty strong GPUs.

CASE: NZXT Source 210 Window ATX Mid Tower Case.  A good, budget, windowed case for everything.  Look into a 120mm fan to pick up as these cases only have one fan.  Any cheap fan should work.  Put it in the front as an intake.

PSU: XFX 550W 80 PLUS Bronze Certified ATX12V / EPS12V Power Supply.  Great PSU.  'nuff said.

ODD: LG GH24NS95 DVD/CD Writer.  If you even need this.  If you don't, save yourself 15 bucks or so and leave this out.

do you have your OS or no?

no I don't 

I mean, I just built a super budget-friendly used PC parts computer. It's pretty nice, and it'll beat those shiny new consoles. Link to the build here:

Honestly, if you want to save money for any reason, this is a pretty good build, especially for the price. You could obviously push upgrades anywhere you wanted to. You could buy newer everything. Get a FX 8350 or an Ivy Bridge or Haswell i5, buy a Radeon HD 6990, or you could buy a newer 7870XT or a R9 280X, if you really wanted to be flush. Alternately there is always the nVidia corner with those low-priced GTX 680s. Honestly, it's up to you.

Did away with the SSD and got a cheaper PSU to fit the budget.  OS included.
