Anybody using the new Mac Pro (trash can) late 2013-2014 for music production? I was going to buy a iMac 27" i7 late 2013 but waited to see what the retina iMac could be, but i am now scared of the reports of spinning fan noise and maybe heat problems in the near future? So now I have iMac 27" i7 late 2013 or new Mac Pro Quad or Hexa-Core to choose from. Not sure which is the best choice, but I am more in to the Mac pro because of the silent fan and the ability to upgrade SSD, CPU quite easy. So now is the big question iMac vs nMP? There is a big price difference but i think that the nMP Hexa-core 4650$ will last a lot longer than the iMac 3800$. Now I have a old iMac late 2006 and it is still going, but it is to old to use for music production now so i need to buy an new Mac soon. If I buy the iMac i can save some money, but I think it will only hold for about five or six years, almost impossible to upgrade. If i buy the nMP Quad it will last three years and then I can upgrade the CPU and extend the lifespan several years. The Hexa-Core is my safest bet, but i am not sure if I take the right decision because all my money will go to just the Computer. Which would you choose and why? I really hope that you guys can give me some good advices here.
