So here are the specifications of my pc.
Amd athlon 760k 3.8ghz
8gb ram
Enough power left in my psu for a graphics card
500gb storage 7200rpm
The mobile has a PCI slot.
The company I want is nvidia. Thanks for your help guys
You could go with a Sapphire R7 265 Dual-X http://www.amazon.com/gp/product/B00IU34RNU but that is the most powerful card you can get without upgrading your power supply. It should handle any game at 1080p though. I wouldn't plan on maxing out settings on Crysis 3 or BF4 though.
