I've been waiting a l-o-n-g time for the updated Mac Pro and I now need to move forward with something. Is there any reason NOT to buy a new Mac Pro at this time? I am a composer/musician and do only audio though I do need to render video to send my music 'roughs' with film clips for the producers/director to see/hear. I was thinking of just going with the latest iMac 5k but I am worried about the machine heating up and also the possible noise. The newest Mac Pro will be fine for my audio needs I believe, so what will the 'updated' Mac Pro have that I will regret not waiting for? Thanks for any thoughts on this.
