I'm guessing that you had some other options picked out in the Cyberpower PC configurator, that aren't embedded in the link. The goals I'd (still) recommend are 16 GB of memory (2x8, so you have empty ram slots for upgrading later), lots of storage (3 TB HDD plus say a 480 GB SSD, or even a 1 TB one if you can squeeze it into your budget), and a large power supply (say that 1000w in the Cyberpower PC configurator for an additional 8 dollars) to accomodate a second graphics card later.
As for the prebuilt one at Newegg, looks like a very nice deal, but the big question would be whether the motherboard has 2 PCIe 16 slots or 3... you want three (for later), but with the mobo 'grab bag' thing, you may not find out how many slots you end up with until after the purchase. Maybe Newegg CS could answer that question for you? The price point might still make it worth it either way though.
As for graphics, definitely shoot for 11 GB of VRAM if possible (unless you aren't doing the Iray thing), and don't settle for less than 8 GB of VRAM (1070/1080). I'm regularly struggling with 8 GB of VRAM (6.4 available after the Windows VRAM tax), but then I like to build slightly more complex scenes with multiple characters - I can manage 4-5 characters usually, if I economize a bit on assets.
It also might pay to wait for 3-4 weeks. The 2080 Tis from Nvidia are supposed to drop this month (around the 20th), and the leaks so far indicate a 35%-40% uplift in performance over the 1080 Ti. Of course, they'll be a bit more expensive, but the upside is that the remaining 1080 Tis should drop in price once the 2080 Tis hit the retail stream. So you might be able to get a sweet deal on a 1080 Ti if the 2080 Ti won't fit in your budget.
Another thought might be (if you go the configurator route) to put in the cheapest graphics card possible, and let the CPU integrated graphics drive your Daz viewport, then pick up a 2080 Ti when they finally drop. Or a pair of (now cheaper) 1080 Ti's... You could use the cheap graphics card to drive the viewport as well, if you keep it onboard. Just make sure to 'uncheck' the box for that card under the rendering options.

I'd also recommend looking very hard at Threadripper. the 60 PCIe lanes (other 4 used by chipset), plus the option to upgrade to a 7nm Threadripper in a year or so, yeah a TR build has some really nice upgradeability options for later. Unfortunately, finding a prebuilt system for less than $2000 could be a challenge, plus it'll probably be a bit low on memory and storage. The 16 Core Threadripper 2950x is receiving a number of good reviews right now.
The downside to TR is no integrated graphics, but you could stick in a cheap card in the 4th PCIe-16 slot for the viewport. To be honest, for regular browsing, the desktop screen lag while rendering isn't that significant, once the shaders have been compiled and the render starts crunching, UNLESS it's a CPU only render. My current system has the integrated Intel graphics locked out, which annoys me 'cuz they'd be great for the viewport, but I manage nonetheless.
The reason that the extra PCIe lanes are important is that Daz Studio loves multi-GPU Iray setups, so building a system with the option to upgrade to 4 GPUs eventually (x16/x16/x8/x8) is a nice way to go. Plus, being able to fall back on lots of CPU cores when you need to do a CPU only render due to scene complexity... yeah.
Also note that a 'dual node' 32 core 7nm Threadripper is a definite possibility, say a year from now. The 32 core Threadripper 2990WX has four 'nodes' which affects memory bandwidth a bit (they are still awesome for CPU rendering though), but at $1800, yeah pricey. If the upcoming (leaked) 16 core 7nm Ryzens become reality and are reasonably cheap, this could mean a cheaper 32 core Threadripper as well. Note that 64 core EPYC CPUs are also supposedly planned...
A dual socket EPYC workstation setup would be nice, especially with the 128 PCIe lanes/8 GPUs, but that won't fit your budget. Or most other people's...
As I just noted, the current info indicates that 7nm Ryzens I just mentioned (which should drop next year) could have up to 16 cores, although Ryzen only has 2 memory channels. Threadripper has 4... Note that the 7nm EPYC/server parts are supposedly on track to drop by the end of this year, which should give us a bit of a sneak peek r.e. 7nm Ryzen...
AMD has been stating for a while now that the 7nm parts will work in existing Ryzen (and EPYC) motherboards, which will be nice if you are looking to upgrade later.
Intel isn't standing still either, but there's not a lot of info yet about Intel's next gen processors. Yeah there's the 9700's, but those are mainly just improving upon existing processors. and the Intel HEDT processors are still rather pricey... And of course if you are looking to buy in the next four weeks, it won't matter anyways.
If you should ever decide to go the 3Delight, etc. route, i.e. a render engine that doesn't support GPU rendering, yeah more cores better, depending on clock speeds.
But enough about that. Just pointing out another way to go. Nothing wrong at all with a decent Intel setup.
