If you want to have a stable system when overclocking 3GHz --> 4.5Ghz, it's a good choice.

Wow, you need to spend that much for decent voltage regulators?

Yeah, the ROG does command a premium. Good hardware quality but I think most of the extra cost is due to all the add-ons (e.g. premium onboard sound chip). It is a gaming motherboard after all.

However, never ever skimp on motherboard if you're planning to overclock :)

A lot of that iMac's cost is its retina display, and you didn't bother buying a retina display for the PC. Running a speed test is silly, there are already major differences in the build. To make this remotely more scientific, you'd either need to buy a 4k monitor for the PC, or use a Mac Pro and just take the monitor out of the equation.

Maybe people already have good enough monitors they can just plug into a PC without having to buy a new one every time they update the hardware?

The article also leaves out the cost of their IT guy's time to assemble the custom PC components. How much does an hour of Joseph WU's time cost? How many hours did it take for him to order, receive, unpack, and then assemble the components?

My guess would be most of Wu's time was spent researching which components to order, probably several hours. On the other hand, if he's a full time employee, then it does not cost anything extra to have him do his job.

If he is a full time employee then the time he spent researching and assembling this computer was time he didn't spend doing the job he was paid for.

60 hours is easily lost when some piece on your custom rig dies and you don't have apple care.

Hyperbole! What piece could possibly take 60 hours to order, receive and replace?

The same pieces that took four days to arrive via courier in the first place?

I'm surprised by HN's response here. I always thought it was common knowledge that a custom PC would be faster than a mac. You don't pay for speed with Apple, you pay for user experience.

> you pay for user experience

Which isn't vastly relevant in a single-application-suite workflow. It's end-to-end Adobe so you plug your SD card in, it copies some files out to an Adobe library and you edit them in Lightroom.

I think many of the problems people are describing is more to do with what's being compared in hardware. Different monitor resolution, different CPU, etc.

My own objection is buying top-end rubbish from a photography equipment supplier. You can get similar spec stuff and much cheaper. This seems to be an exercise in trying to spend $4k (which is actually quite hard when you're not buying a Mac) rather than building for value.

$630 for the graphics card is a waste of money for Lightroom. Should have spent it on PCIe SSD or Xeon CPU.

I don't think you'll get higher single core speeds on a Xeon...

Some operations is Light room scale rather well with the number of cores, and some do beyond 8 cores.

That spec iMac is currently $3879 at MacMall [1], To save money, you could easily spec a 4.0GHz/8GB/1TB FUS/M390 for $2299 from B&H [3], add the same SSD ($300) and ram from OWC ($328 for 32GB / $667 for 64GB). Bringing the total to $3266. We also need to go to a 5K 27 inch monitor on the PC side for a fair price comparison; the cheapest I could find was $1042 HP Z27q [4]. Add $42 to the PC price to make up for this.

Now, the PC price comes out to $4370+42=$4412, so we need to drop $1146 of from the PC to get a realistic price comparison. The RAM, Screen, SSD, and graphics card are anchored due to our Apples to Not Apples comparison. That leaves the motherboard, case, CPU, power supply and water cooler to drop in price.

I don't know water cooling particularly well, but lets say we leave that in to continue overclocking the CPU, but drop to a lesser model, same with the Power Supply and Case. So revised budget for each is:

Case: $125 -> $80 Power Supply: $140 -> $80 Water cooling: $120 -> $80

Now a gaming motherboard was selected because it's stable for overclocking, but let's throw caution to the wind and drop our budget to half that and hope it still overclocks stable. $480 -> $240

That leaves $261 for the CPU, which buys an i5-6600K (3.5GHz), or we drop the water cooling and run everything at stock to get to an i7-6700K (4GHz). In other words, the same processor in the iMac. If this benchmarks any differently, it's the Lightroom developers fault, not the hardware.

So, the upshot is, spending the same amount on a Mac will get you the same specs in a much better looking equivalent device.

Apple is delivering a turnkey hardware solution with the 5K iMac. They will also provide an upgrade path with future hardware generations. This article is the same-ole myopic view of DIY specifications and IT enterprise management. Macs are not built for people who can or want to do it themselves. Macs are built for people who ONLY want to focus on the task at hand.

Unless 'researching, building and supporting the IT environment' is his job, as their IT guy
