Can't choose a GPU! Help?

It's finally time for the fun part of my build! Picking my graphics card. Ugh, but there's so many variables, so many benchmarks, and reviews, and possibilities! I need some suggestions and the community's input. First of all, please understand I have no bias to AMD or NVidia, and would gladly purchase either or. Now that that's out of the way, here are the parts that I have already purchased and plan to also buy:

Case: Fractal Design ARC Midi R2 

PSU: Rosewill Green Series 530w (plan on upgrading in the future) 

MoBo: MSI 970A-G46 

CPU: AMD FX-8320 Vishera 3.5GHz 

CPU Heatsink: Corsair H55 Liquid CPU Cooler 

RAM: G.Skill Ripjaws X Series DDR3 1866 (2 x 4GB)

Storage: Western Digital WD Blue 1TB 

GPU: *??????* 

Now it's worth nothing that I'm not planning on spending more than $300 dollars, so lets try to keep it in the $200 - $300 range. So far I've been looking at these cards: MSI R9 270X HAWK // HIS IceQ Radeon 7850 // MSI R7950 // EVGA SuperClocked GTX 760 // Gigabyte GTX 760 Rev 2.0 // MSI N760 HAWK GTX 760 

So it's a pretty long list, and it's quite a dilemma. Help?


**EDIT: It's worth mentioning I'll be playing a lot of BF4 along with Video Edditing, streaming, photoshop, and 3D designing.

get a 990fx chip set motherboard because your fx 8320 will destory anything with a weak power phase set up. and for the GPU get a hd 7970hz editioin.

That's a bummer, I already purchased the board. Thanks for the input though! I'll be sure to consider that GPU. Looks like I have to get a new motherboard. I knew that the 8320 wasn't very power efficient, but I thought this board could handle. Thanks!

R9 280x

Any reason why you choose that?

It's a update/upgrade 7970. It's very cheap, will be great for any game at 1080p, and easily fits in your power budget.
