PC or MAC...?

I have been a Dj and music composer for over 15yrs and now I have an interest in video editing. The Pc I have now is cool(toshiba satellite)but it needs a major upgrade. I checked-out how much it was going to cost me to upgrade and thought, why not get a new Pc or Mac? I've done my research and I've made up my mind, but I still would like to know what you guy's think. Should I go with a Macbook Pro or Pumped up Pc..? Please guy's...give me your balanced opinion's. lol
