Hi,
Im getting ready to update from my late-2009 27" 2.66Ghz iMac to a 27" Retina iMac
When you were testing or evaluating what did you see as the real world differences between
- the 3.5 GHZ Quad-core i5 or 4.0GHz quad-core i7 processors?
and the
-AMD Radeon R9 M290X 2GB GDDR5 vs the AMD Radeon R9 M295X 4GB GDDR5 ?
I am planning on going with the 512GB Flash storage for boot drive and applications, and will max out the RAM (from OWC).
Thank you,
Ellis

Hi Ellis
I recently bought a retina iMac. I went for the higher end processor & graphics card since they're not user upgradeable & only added 20% to the price of the iMac. I went for the 256GB SSD option. This drive only has OS / apps on it - Lightroom catalogue / PS scratch & some working files are on a thunderbolt 500GB RAID 0 drive. Most files / Time Machine are on external USB 3 drives. 32GB RAM from Crucial.
I'm still setting the machine up ( & getting pissed off by Yosemite ) but initial impressions are positive. The screen is marvellous. For the first time I feel like I'm looking at an actual photo / artwork rather than a bunch of pixels. Colour matching to prints is good enough for me ( on a par with my NEC PA231 Multisync ). I calibrated it using BasicColor & a DTP94 puck.
Photoshop CS5 runs well on it & Lightroom 4 is OK: I was getting some weird graphics glitches in the print module a couple of days ago but nothing like some of the horror stories I've read on the net. I'll be trying out PS / Lightroom CC soon.
Wish I could get my Microsoft Intellimouse working properly, the 'Magic' Trackpad will be flying out of the window soon. ( Actually thats not fair, the trackpad is OK I'm just not a trackpad guy ).
Enjoy your new iMac.

Hello Graeme and thank you for your prompt reply.
The point you make about difference in cost is a good one. My experience is that I get about five years of heavy use of an iMac so amortized over 60 months it isn't that much of a cost difference is it?
A 256SSD is a little small for my needs - if I keep my Lightroom catalog on the boot drive.
Which graphics option did you go with, the AMD Radeon R9 M290X 2GB GDDR5 vs the AMD Radeon R9 M295X 4GB GDDR5?
-
I went for the M295X 4GB GDDR5 option. Thought it might help with the sheer quantity of pixels that the thing has to display & possibly remain compatible with various software upgrades for longer. That might be wishful thinking.
I was impressed with the Retina iMacs value for money compared to the regular iMac. I configured them both on the Apple Store ( best processor & graphics available ). The retina version wasn't really much more expensive & had slightly higher spec components.

PS When you come to upgrade your RAM there's a brilliantly designed little cover on the back of the mac that pops off when you press a little button by the power lead socket. Well it would be brilliantly designed if it did actually pop off. Ended up using the sucker on one of these to get the thing off.

I have decided to go with the 5K Retina iMac and will configure it this way:
Processor: 3.5Ghz i5 processor
RAM: 8Gb (stock configuration , will immediately upgrade to 32GB RAM from OWC)
Storage: Originally I was thinking that I would go with the 256GB Flash, but after doing a bit more research and thinking about my needs and from what I've read about Fusion at http://www.anandtech.com/show/6679/a-month-with-apples-fusion-drive , I have decided to go with the 512GB Flash memory option.
Graphics: no question: the AMD Radeon R9 M295X 4GB GDDR5
Here’s the tricky part. Do I buy now or wait to see if t an update to the Retina iMac is announced at the June Apple WWDC or at a product launch in August? I suspect any update will be fairly minor.
-
We have a pretty good Mac tech support guy in our office, and I ran these questions by him last week, since I have to replace my 2009 27-inch iMac soon.
The processor upgrade is a total no-brainer - do it. The i7 makes a big difference in processing power, like exporting from Lightroom or building previews.
He was not sure about the video card, but suggested that since LR and some other apps can now use the processors in the video card that it is probably worth the upgrade - I need to do more research on that one.

Hi Ellis, I too have been watching apple because I need a new computer. I found this this morning. Just a rumor. So maybe it will be wwdc announcement.
http://www.macrumors.com/2015/05/18/15-macbook-pro-27-imac-expected/
Maybe worth the wait. Maybe not. These days I'm never sure if apple will disappoint or not. I personally want a new macbook pro but waiting to see what they do. I may just try and order the current version if I'm not happy with what is changed.

Went with a 27" i7 4.0 Ghz model with the more powerful graphics processor and a 512Gb Flash drive. I saved $500.00 by buying it through Apple's refurb store. This configuration, because I bought it on Apple's refurbished site, came with 16GB RAM installed. I am adding 16GB more RAM (from OWC)
Here's a possible tip: if you are looking buy from Apple's refurb store, Apple seems to repopulate it at 6pm Pacific time, if not daily then they definitely do it at 6pm on Friday nights. I had been looking all week and several different ones appeared at 9:01 that were noter at 8:45pm.

Has anyone looked at the issue of color gamut and calibration with the iMac monitors? The new 5K ones are sRGB only with respect to gamut, and I've seen complaints that they do not calibrate well.
I am thinking of going this route, but don't want problems with poor color fidelity...
If they are less capable, I suppose one option would be to connect them with a much better second monitor for the main editing and palette screens.
Ellis, what do you think so far of your purchase?

Hi Michael
As I mentioned in my earlier reply to Ellis, I calibrated my retina iMac using a DTP94 puck & Basicolor Display. I bought Basicolor for my NEC PA321 Multisync. ( This display is a step below the top end Spectraview displays ).
The iMac display works perfectly well with this calibration setup & in fact Basicolor reported slightly better delta measurements for the iMac display than for the NEC. ( Fair enough - the NEC is 3 years older ).
I haven't done too much colour work with the iMac yet but my initial impression is that the colour accuracy is good as the NEC .
( The colour work I do consists largely of preparing prints of my partners stained glass designs to present to clients & also prints of her completed work. I have to deal with a lot of very saturated, often unprintable colours so I need a monitor setup good enough to give me a decent soft proof. However, I've never felt that a 'top end' display setup would be a justifiable expense for me. Your requirements may be quite different ).

Thanks...
I shoot primarily for B&W, and I'm worried about having decent linearity in the image, especially into the highlights, where I've had trouble in the past getting the monitor to fairly represent the file.
I do end up with a lot of color images, but all of "my" work is the B&W...
I'll look into it a bit more, but I think the iMac is going to be the computer to get for me.

OK, I have a machine on order...
Does anyone know how far back I can go with the OS in a dual-boot setup? I have a scanner that is a few years old and can't go higher than 10.6.8, so my current Mac Pro has a dual boot setup on it so I can use it when needed. I'll do some research if nobody knows and report back.

Michael,
I'd be surprised if you have any success in running any OS older than Yosemite (I suppose you might get away with Mavericks), at least natively. If you really can't find updated drivers for your scanner, your best bet might be to run 10.6.8 in a VM under Fusion or Parallels. I'm not sure that that can be done, but I suspect the odds are a lot better than those of successfully installing an old native OS.

Hahaha, yeah, I sort of figured that would be the case.
No chance of drivers. Microtek abandoned the Apple platform a while ago and Vuescan software doesn't seem to work properly with it (I get horrible scans with Vuescan).
I may have to try Vuescan again once on the iMac, because maybe it will work better on the new machine. That would be nice.

Can you successfully do 5000k?

I don't know Craig. I tend to use either native white point or a reading taken from my ( low tech ) viewing light reflected from one of the papers I print on. When I get time I'll try it & let you know. ( Busy with deadlines at the moment ).

You could try running Windows under a VM, if you can get up-to-date Windows drivers. That would almost certainly work.

The release for the RAM cover is a button at the top of the recessed AC connection.

After a couple of weeks with it. I am pretty happy. Lightroom with the GPU enabled is pretty zippy. Photoshop is very fast. As expected the gamut is close to sRGB and the display profiles nicely with using the Xrite i1 Display Pro and i1 Profiler. Setting for profile are Gamma 2.2 and 120 cfm for brightness

another update. Just did my first stitched panorama with the the new machine using PTGui Pro. It was shot back in 2010 with a Canon EOS-1D Mark IV, and consisted of 2 rows (38 frames total). The DNG files were stored on a Drobo 5D connected to the computer via Thunderbolt. I exported the 38 frames from Lightroom CC 2015 (very fast with GPU enabled) as 8-bit per channel TIFFs to a file on the same Drobo 5D and instructed LrCC to open in PTGui Pro
And that is where things got very, very fast.
I have stitched this particular panorama, a skyline of Austin, TX, before and back then the PTGui process Back then it took about ten-fifteen minutes as I recall for the entire process of editing, stitching and exporting as a layered PSB file. This time it look well less than 5 minutes and Iwas ready to edit the stitched and layered PSB file (3.3GB) in Photoshop CC 2015.

Thanks for the updates, Ellis. I'm in the same position you were before the new machine, and this is very helpful.
My iMac is my personal machine, though, for the little freelance that I do and any personal work. So even though it has slowed to a crawl, it's hard to drop three grand on a new one. :) But I'm just going to have to bite the bullet and do the upgrade this year, and I want to get a machine that will last another six years, or more.
-
I think you'll be pretty happy. But I really expect, based on past experience with multiple computers (Apple, IBM, NeXT) and given the increasing speed of technological changes that expecting six years or more of service out of a computer is being wildly optimistic. But of course it will depend on how hard you make the machine work and what you do with it.
