So as the tittle ask Im wondering what I should upgrade next? Below are my current specs as of 3/29/2013.

I am asking you as the community which component you thing would be my best bet to upgrade! Please let me know what you think!

Current Specs:

• 
  HP Pavilion HPE
  Processor: AMD FX-6120
  GPU: Zotac NVIDIA GTX 660 AMP Edition
  8GB DDR3 Ram
  1.0 TB HDD
  PSU = HP 460W (Dont know to much on it)

My thoughts:
I was either wanting to upgrade to 16GB of ram or get a better power supply (700W).


Please let me know what you think!
