Hi, I just need some advices about the GPUs.

I'm gonna buy a new GamingPC and I am between 2 GPUs:
The MSI VGA PCI X R9 270X Gaming 2GB vs Sapphire R9 270X 4GD5 DX Boost OC

The query I have is: The Memory of the one GPU is 4GB and the other's one is 2GB. What difference there is between these 2 GPUs?
And which one is the best?(Also, if there is a better GPU in the same price just let me know :wahoo:)

My System:

CPU: AMD FX-8320 3.5GHz 8-Core (I will OC it at 4.1 with Cooler Master Hyper 212 EVO 82.9 CFM)
Motherboard: Gigabyte GA-990FXA-UD3 ATX AM3+
RAM: G.Skill Sniper Series 8GB (2 x 4GB) DDR3-1866

Thanks in advance!
 
Solution
The higher VRAM they have is mostly for large monitors at high resolutions and multi display setups. If you are using under 27 in at 1080p 2GB of VRAM is enough.
