I do heavy editing for living. I use a Mac Pro most of the time. I wanted to clear a few things people may not realize when buying iMacs. They do get hot depending on what you render. Video rendering is one task that requires a lot of processing power, especially at the final stage. So if you are exporting a 1080 HD or 4K quality, you will need more processing power. A lot of people gets stuck with the question of "More RAM" or "Do I buy i5 or i7"Here is the bottomline:If you are on a budget and not monetizing your work, stay with i5 quad-core and increase your ram to at least 16GB. It helps to have a 4GB dedicated graphics.If you are already earning some dollars from your work/edits, no brainer to go to i7 and higher RAM. You will hear less of your fans kick in and your iMac will run much cooler. If you are rendering a lot, one cannot avoid iMac getting hot. People don't realize how hot because you are not keeping your iMac on your lap like your Macbook Pro. I STRONGLY suggest getting Apple Care! It is more than a piece of mind! Super beneficial. I NEVER hesitate rendering a 50GB video and how hot my iMac going to egt and melt something inside. I am covered. And the best part of Apple Care is what it adds to your iMac's value. It is so much easier to sell with a better price. Buy a 3 year Apple Care and sell your iMac before it expires and buy an upgrade. It is a great cycle! I am always on a newer iMac with better specs. Very dependable and consistent results for my work.Please let me know if you have any questions. I do not work for Apple but I can help you make a decision if you tell me what you need an iMac for. I can literally give you a few specs that would save you $100s.
