So far, a few weeks into using this new build, I absolutely LOVE this CPU. I primarily use this machine for photo editing with PhotoMechanic, Adobe Photoshop Cloud 2017, and Capture One Pro 11. This CPU can handle everything I throw at it without breaking a sweat. Even when I've run a 1000 image export in Capture One Pro, a 500 image batch process in Photoshop, I could go back into Capture One Pro, open a new job, render previews, and start RAW adjustments with absolutely no lag. It worked flawlessly. The RAW adjustment sliders are silky smooth, with no lag. Best of all, the CPU temps have remained an average of 55C under load at 4.4GHz overclocked. At 4.6GHz, the temps only averaged 70C - spiked to 76C a couple of times. I'm using the NZXT Kraken x52 CPU cooler. Works for me.
For Photoshop, an application that prefers high clock frequencies vs. more cores, I love that this CPU has the same 4.5GHz Turbo Boost frequency as the Intel 7700K. That's incredibly impressive for an 8-core CPU. The 7700K, used to be the Photoshop king, but I would bet there is little to no real world difference between this 8 core 7820x and the 4-core 7700K when doing lightly threaded Photoshop tasks. The 7820x is so responsive.
IMO, this CPU might be the best bang for the buck in terms of single, dual and multicore threaded applications. When you factor in the 28 PCIe lanes over the 16 PCIe lanes you get with the might i7 8700K, I still have to give the 7820x the nod. If you only need 16 PCIe lanes, then the 8700K will save you about $200 on the CPU, and maybe $50 on the Motherboard.
With the 7820x you'll want a good Motherboard. Should go without saying, but that doesn't mean the most expensive.
After tons of research about VRM issues with the Skylake-X CPUs, I bought the ASRock Extreme4. The two features I wanted most were, dual 8-pin CPU power connects, and the VRM heat pipe. Intel shotgunned this CPU family release, and IMO it caught the MOB manufacturers off guard, and many release their MOBs too quickly. EVGA wouldn't even release their MOBs, as they hadn't been thoroughly tested. These CPUs are power hungry, and if you OC without a good cooler, VRM cooling, and adequate power, they'll overheat and throttle.
New and 2nd Gen x299 boards are already coming out with these dual 8-pin connects and VRM heat pipes (Taichai XE is one example of a Gen 2 x299 MOB). The Extreme4 is a new board released in November, a good few months after the release of Skylake-X. So they had time to get this board right, and it's one of the least expensive boards on the market.
I had a limited budget of $2,000 - and if I could do it all over again, I would definitely buy this build again.

So far the only issue I have had was the switch from the Intel Windows application managing Turbo Boost 3.0 to native Turbo Boost on the 7900x. The application would just crash saying the system was not supported and confused me for a bit. I then found out that once you have it running natively you no longer use the application. I removed the application and all is well. This seemed to happen when I updated the MB BIOS from V4 to V5 so this is an example of the growing pains we may have to deal with. Still worth it though IMO.
Edit - 07092017:
I have finished my custom water loop and took some screen caps from Aida64 while Idle, stock stressed, and 4.6GHz OC Stressed. There has been a lot of talk about the temperatures and power with the 7900x so I hope this info helps anyone checking it out.
Edit - 08032017:
Processor has been running flawlessly at 4.8Ghz for about a week. I am also running the mesh clock at 3.2 Ghz, up from 2.4 Ghz stock. I will get some pictures of benchmark results and throw them up here when I can.
