That's a question you'll need to answer before anyone can determine what would be best for you.
A *pure* gaming machine would be best served by an intel chip, whilst streaming while gaming swings in AMD's direction. Take some time and figure out what you will be using the machine for and order of importance and give us that list (e.g. video editing, virtual machine's, etc).
If what you will be using the machine for most favors strong per-core performance, you're likely better off with Intel. If you need heavy multithreading, consider AMD.
If you mostly play LoL and CS, both options provide far more performance than either game needs.
