I need some help in picking parts for a photography specialised rig. Well more so to make Lightroom as zippy as possible thing is I haven't the foggiest where to start..

What chip do I need a 6700k or a 5820k? Now that the 6900k has been kinda unofficially leaked should I wait for that.

Also I want to add bucket loads of RAM. I use so many application open at the same time that I don't want to impact anything else just because I don't have enough. I'm sure the more I have the better anyway not sure if I wanted to add 32GB maybe even 64GB. I say I want a bucket load but I also want the very best value for money, having watched this video https://www.youtube.com/watch?v=_WsfeuWI7mU RAM Latency vs Frequency by ThioJoeTech I found this table he created click here and anything in yellow under 10 ns is worth buying and is going to help my rig right?

So motherboard, jeez all I look for on a motherboard is plenty of SATA ports, PWN so I can control the fans on the computer and something that is compatible with the above two parts really. Perhaps provision for a M.2? Lot's and lot's of USB 3.0. But wait, is there anything that Lightroom should require from a motherboard that I've missed?

Use a SSD as your working directory and you will be impressed at how fast your current rig handles Lightroom image adjustments.

Do you work with RAWs or JPEGs?

Also, certain things like preview size and quality can MASSIVELY hog down Lightroom, so it's a good idea to optimise that first as you might have zero need to generate maixmum quality full resolution previews on the fly, and there is a lot of performance to be gained (especially if you're visually previewing them and not batch editing).

Lightroom and Photoshop are pretty much still single threaded so a good 6700K Z170 system will be perfect. 32GB of fast ram will be more than enough....running more RAM like 64GB will put more stress on IMC (memory controler) and you might want to lower frequency to have a better chance of running stably.

Get a 500GB 950pro in the M2 slot as your OS drive

Good GPU can help http://www.nvidia.com/object/adobe-lightroom-cc.html

Not entirely correct, for example Lightroom export jobs are very multithreaded, as are Photoshop filter galleries and such - the program just tiles the area to be redrawn.

Try a RAW export job in Lightroom and see it by yourself.

There is very little filter gallery effects to be used within Lightroom, it's mostly digital developing of RAWs and gallery management.

I'm running a fairly large Lightroom catalogue on my 5820k 16gb ram system.
The largest performance gain came from running my os on an M2 drive and putting my catalogue onto a 512gb ssd.

Any modern system should run Lightroom nicely.
Hdd performance is the best way to speed things up.
Once things are cached into memory it's very smooth.

The 5820k is much faster than my old amd system when exporting large batches of jpeg, but I'd expect skylake would also be fine for me also.

I'm processing 24mb d7100 raw files.

I would look for usb 3.1 or typeC as faster file import is nice, especially as file transfer speeds and sizes should go up on newer cameras.

I wasn't sure, I had never had a monitoring program open when I was using Lightroom, so I just tried it. It used all 8c16t of a 5960X to some degree. None of them went very high on usage, but I only imported a single FX RAW and converted to jpg, and only a couple of the cores hit the max turbo OC speed of 4.6GHz - but it used more than a single.

Your 5960X will smash a single export before the task manager will even see a jump in activity,

Try to export 10 or 12 pictures and you'll see it works on several files at once.

My 2c is that LR is multithreaded, but unlike rendering engines for example, it doesn't scale well indefinitely.

Depending on the version you are using, there are actually diminishing returns even going to a Hex core, if that comes to the expense of clock-rate. For example a stock 5960X will be worse than a 6700K in most real life scenarios.

Core utilization got better with CC 2014/2015, but still cannot hit 100% utilization on my ol 3930K. It actually uses 7-9 / 12 threads tops. A higher core-count would be pointless.

Before CC 2014, it was actually common practice to export large jobs in 2 parts simultaneously, to see benefits from your multi-core CPU, now returns are diminishing with that practice but you still do "more" per second.
Running more than one export jobs is still beneficial if you have a 2P system and enough RAM (I work with 20-24MP files and it utilizes a tad over 8GB when exporting. More than one jobs don't multiply that, just increase it slightly).

Whether you go for a 6700K or 5820K and apply a mild o/c to either (more beneficial for the 5820K), it will end up being a wash at the end due to LR inefficiencies working past 6-7 threads.

The best performance advice is to actually use a dedicated SSD for your LR working catalog. If you do PCIe, its better. Have catalog and pictures-2-b-developed in that, export and move it to your HDD / DAS / NAS or w/e you "cold-store" it at to free up space if you are running low. Keep the working catalog clean of photos you are not working with, and use another "main catalog" for the completed jobs - even if you do have available space in your SSD.

Only select filters and effects are threaded, very few will utilize beyond 7 cores and even fewer beyond 2. Photoshop and LR are very much 90% single threaded and a core I7 is the ideal CPU for it for a good while. I would look at getting an i7 rig with as much ram as you can and an SSD, if you can put a decent GPU in thats great too, and a K series would be nice with an overclock but not necessary.

My personal recommendation is

CPU : i5 at least, prefer i7 with highest clocks you can get
Ram: 16gb or more depending on the image size and number of layers you use
SSD is a given and w.e size you can get
GPU: unless its gaming rig too you can be just fine with anything in the 100-200$ range.

My 2c:

Lightroom is one of my main applications. It runs very well on my PC. I use a 5820K CPU, X99 motherboard and have a 980Ti GPU. Lightroom application is on an M.2 SSD. However my RAW files are on a 7,200 HDD. I use the preview files or whatever they are called and store them on my M.2 in order to do basic editing. These edits are applied to my large RAW files when outputting results.

My rig is now 2 years old and not totally optimal. The HDD is the biggest limitation on my system and I am thinking about upgrading to another SSD for RAW storage with a NAS / HDDs for archive. If I was starting from scratch I would choose a Z170 motherboard, 6700K CPU, 1080Ti GPU. 1 or 2 large capacity M.2 SSD and 2x 32GB memory (few large sticks). Make sure the motherboard you use as M.2 drives using PCIe 3.0 not PCIe 2.0.

The main things you can do to turbo Lightroom is 1) High GHz CPU (4 core, 8 thread is plenty), 2) Use SSD, preferably M.2 PCIe SSD, 3) Powerful GPU, 4) Enough memory... 32GB should be fine. Memory speed unimportant.
