That's only a $4 savings on that combo? HAH! Ignore that, it's too small a savings (especially on a 3-item combo) to matter.
You can often do better buying individual parts, with promo codes, than you can combos, unless the combo discount is significant (like $30-40 or more off).
BTW, 3rd-Gen Ryzen is out. Availability may be spotty, but I suggest getting a Ryzen R5 3600 or 3600X CPU, and then check for combos on the CPU's pages under "Combos", for mobo + CPU combos (maybe + RAM too), of $20 or more off.
Also, check the rotating banners on the front page of Newegg, they have a few that lead to some more combos, and I think that they have some 3600 + B450 or X470 combos, as well as the X570 combos.
X570 really matters only if you want PCI-E 4.0 for dGPU or M.2 NVMe drives, and/or want to run two RAID-0 NVMe SSDs. (I have that on my Asus ROG STRIX B450-F ATX board, with my Ryzen 7 2700 @ 4.0Ghz, 1.350V, and a pair of Intel 660p 1TB NVMe PCI-E 3.0 x4 SSDs.)
I know for a fact that the Gigabyte AORUS PRO WIFI B450 ATX board has a BIOS (F40) that will support the new 3rd-Gen Ryzen CPUs. It's also on sale from time to time for $110. So, $200 for the Ryzen R5 3600 (or $250 for the 3600X), $110 for the board, and there are some 32GB kits of DDR4-3200 for roughly $150-160. So maybe $500 inc. taxes and shipping from Newegg for CPU/mobo/RAM.
I can't tell you until I get my 3600 in my mobo and get a PCI-E 4.0 x4 SSD, if that combination will allow for running a PCI-E 4.0 NVMe SSD, but I am hopeful that it might.
For PCI-E 3.0 x4 NVMe SSDs, there's the venerable HP EX920 and EX950, and the new Patriot Viper 1TB one, that's currently $130 on Newegg, it's a Phison E12 controller with TLC NAND, supposed to do 3500MB/sec read / 3200MB/sec write, I think. One of the faster PCI-E 3.0 drives.
Cheapest 1TB NVMe, is Intel 660p 1TB for $87 or so, or 2TB for $177, on sale. Those are slower, sort of, but still decent overall, and way faster, than SATA, while not really costing any more than a decent SATA drive. Plus, they're from Intel, which means that they should be reliable as any other 1st-party SSD.
Edit: After looking at the combo deal pricing, that you linked, it's not awful, really, but I would personally choose better parts, and the 2600X price is so close to just getting a brand-new 3rd-Gen Ryzen R5 3600, that I would spring the extra $20-30 for the 3600. If you can find one, I think that the lowest 6C/12T Ryzen 3rd-Gen CPUs have better availability.
