[Dpg2172]

So as per title, i am planning to buy GPU with FX6300.
GPU are: R9 270X 2gb or R9 270X 4gb or R9 380 2gb, all supphire versions.
I am getting these GPU around 15000-16500 INR in india.
So which will do better at 1080p in years to come.
Help is much appreciated.

380 2GB

IMHO, By the time you need more than 2gb in the 270X you will be out of GPU power.
