It sounds like the 5K Retina iMac isn't necessarily what you need. If that's the case you can probably find a refurbished slightly older non-5K 27" iMac with better specs (i7 processor, upgraded graphics) for about the same money as a lesser equipped 5K.
For all its good looks, a 5K is just a monitor. It's what's inside that really defines your computing experience.
Yep, right up until the point where the computer stops functioning. But hey, it's a really nice looking crash.I have to disagree with this, all of your interaction is through a computer screen and the better it is the better the experience…
5k is definitely nicer but it's also definitely not needed. I still have a 2009 iMac and the screen looks great. Not everyone needs the absolute top of the line machine.I have to disagree with this, all of your interaction is through a computer screen and the better it is the better the experience, my 13 inch rMBP is great but my favourite thing is how good text looks on a retina screen it's like reading top quality print. Most people don't need massive CPU power, huge amounts of RAM, or top level graphics but they all benefit from a great screen. They also seem to be much easier on the eyes when using a screen for any length of time.
Given that the OP started this thread last year, the odds are high he's already made his decision and purchased an iMac.Hello OP, if you're absolutely set on an imac and are considering getting a used one, definitely avoid the 2011 27" imacs.
