Hi All, I am about to buy my first mac after being a PC enthusiast for the last 20 years or so. It is for my business (HD film editing) and I was going to either get a Mac Pro or a iMac. My budget is about £4000 and I want whatever will reduce my workflow. (My PC spends half it's time crashing Premiere and then takes 20 mins to recover). I have heard that there is a new Mac Pro on the horizon but there is no confirmation and that the iMac has had a recent upgrade to make it a pretty quick machine. I have also heard however it is prone to overheating, especially considering what I will be throwing at it. (Pretty much constant rendering demands). It does, on the other hand, come with a monitor. I can't really make up my mind as I am a complete Mac novice so any advice would be greatly appreciated.
