What is a good gaming pc for £700?

I'm looking to buy a gaming pc as I have no idea how to build on myself.
I would mainly be playing Battlefield 4, but I would play other games like minecraft as well.
My price range would be a maximum of £700, although it could be a little over.

My humble suggestion:
