Don't shoot if this sounds too much like a newbie question. I have had three Macs over the past ten years. I had a 15" MacBook Pro (2008 model), a 11" MacBook Air (2013 model), and now a Retina MacBook Pro (2013 model with 16 GB RAM, 512 GB SSD, intel i7). I have also had a handful of PC laptops, which aren't worth mentioning except a tank of an ASUS that I bought for $500 and for some reason just keeps going strong. The other ones lasted four or five months and always went straight down the drain. I'm a Mac person, and I want a powerful home work station. I work in international development and do a lot of video and photo editing, creative design, and multitasking. I know I probably don't "need" a super powerful machine. But working on my Retina MacBook Pro isn't as practical as working with a big immersive screen with a lot of power behind it. I would also like to game on it sometimes - Call of Duty, that kind of thing. So the questions is: iMac or Mac Pro? I love the 5K Retina iMac but I have heard about a lot about overheating problems. I also never know where I am going to have to use this thing. Sometimes I work in Ghana, Ethiopia, South Sudan, but will hopefully be mostly based in Portland, OR. So heat could be a major factor - it has been for my MacBook Pro in the past (It gets to be 108 degrees on average in South Sudan). Ideally I will be in the United States now, because I have kids that need to go to good schools (which there aren't in South Sudan, unless you have $50,000 a year to spare). So my biggest question is which of these two options is the most durable and sustainable? I worry about the all-in-one nature of the iMac. That is, it being hard to tinker with and fix. But a Mac Pro at least has the option of swapping monitors, replacing memory, etc. Then there is the price. A Mac Pro plus a monitor is a a huge price to play. Better to go iMac and then just swap it out when it dies? Or better to go Mac Pro? Thoughts?
