Need help with upgrading GPU

[TheChromeDrone]

Hello,

I'd like some help/recommendations on upgrading my GPU, I have a HD 7750 and it was viable at the time that I bought it (which was about 2-3 years ago).

It can run games up to 2012 fairly fine on high settings with my native resolution (1600x900), but anything newer can only run on low-med settings.

I'd like to play current gen games (Witcher III: Wild Hunt, GTA V, Batman: Arkham Knight etc) with a smooth 60fps or at least run them without dropping below 30fps on high-ultra settings at native resolution.

 

These are my current specs as of the time this is posted:

PC Part Picker

MOTHERBOARD: Asus P8H61-M LX3 R2.0

CPU: Intel Core i5-3470 3.2GHz Quad-Core Processor

GPU: Asus Radeon HD 7750 1GB GDDR5 (10% OC'd)

RAM: Kingston 8GB (2 x 4GB) DDR3-1333 Memory

STORAGE: Western Digital WD5000AAKS 500GB

PSU: Corsair VS 550W ATX Power Supply

CASE: POWERLOGIC Azzura 3000

MONITOR: Samsung S20B300B 60Hz 20.0" Monitor

 

Based on the Mobo, PSU and CPU, is it possible for me to upgrade my GPU to either a Sapphire Radeon R9 280X 3GB Vapor-X or a ASUS Strix GeForce GTX 960? Is it worth the upgrade or is it only a slight improvement? Will my CPU bottleneck the GPU? Is my PSU enough to power them? Are they future proof?

I'm on a tight budget which is around $315. If you have any other recommended alternative GPUs then feel free to enlighten me. Just nothing above my budget.

Also I can only buy the parts locally due to reasons I don't need to explain.

go for the 280x, major improvement. but if u can stretch to $320, go for the gtx 970

Is the Palit GTX 970 (not the Jetstream one) good enough? I read that it doesn't have a great cooler... Also the price difference between the normal and the Jetstream in my country is about $42 and the price difference between R9 280x and GTX 970 is about $30.
