I totally agree with KHSup.
I will add that if you wan't the "smoothness" from Mac OSX, then go for a linux Distro. Get something like Mint, Ubuntu or Zorin OS6 if you are unsatisfied with windows. it is faster, open source, Highly customizable and best of all... it's FREE
(Apple and MS are freaking out now
) if you are going Linux, you might want to save some money on that GPU and get a modern low end GPU for Editing and not so much gaming, sense there are not so many games on linux that require a high performance GPU
