I am getting a budget casual gaming/ work/ web browsing computer for £850 or less and am going down the AMD CPU path. By spending a little more money on the FX-8320 will it improve my gaming/ browsing and video watching performance and is it worth it? I am getting a Nvidia GTX 760 GPU so I am not too worried about gaming but will it affect the general speed of my system because of its lower clock speed? (I don't want to be overclocking because I want to keep the life of my processor since I will not be upgrading for a while after this new build)
