I am looking to upgrade my graphics card and I have narrowed it down a bit and just need a bit of help. I have AMD FX-8350 cpu and Asus Crosshair V Formula-Z mobo. My budget for the gpu is £240. So I have Asus GTX 760 striker 4GB or Asus GTX 770 2GB. If you can think of a better GPU in that price range please tell me.
