I just took delivery of a 27" iMac.

It's a factory order as follows:

Processor - 3.4Ghz i7

RAM - 16Gb

HDD - 3 Tb Fusion

Graphics - standard card.

My main use is post processing and image library management for my professional photography.

I have a second monitor (Dell 27) hooked up via a mini display port/DVI adaptor.

This machine screams through tasks I do a lot. I had to get used to using Photoshop and InDesign because I am prepping files for printing in an exhibition. My 2006 Mac took about 30 seconds to open Photoshop CC - the new one takes less than 3 seconds! Saving layered .psd files is 50% quicker too. Opening and working with large TIFF files is barely slower than JPEG files.

The new screen is much less glossy than the previous iteration and although I still see some reflections they are ignorable now.

The all in one design is actually pretty funky and I quite like the extra space I get back from not having the Mac Pro in my office. I also very much like the fact that compared to a Mac Pro, it runs almost silently.

So just in conclusion, as a photographer's machine or a graphic artist's machine, this spec iMac is awesome.

I'm going to add another 16Gb of RAM to max it to 32Gb. There is an upgrade on the video card which doubles the on board ram from 1 to 2 Gb but I do not render video nor play games and decided that the $250 it cost would be better spent on more RAM.
