If I'm remembering correctly, you have a 4K display, correct? If so, and if you want to use a near-4K resolution, you'll likely be restricted to either DX11 Legacy, or maybe a mix of both APIs in a team, with only 8GB of VRAM on that 2080. Other than that, everything looks to be okay. Also, you can save money on an OS if you're willing to purchase from a source that would be considered outside of the "retail market," like /r/microsoftsoftwareswap. I've purchased several keys from this guy, all of which still currently work today, without issue.

However, I do just want to point out that AMD is releasing new CPUs in June, which are, almost without a doubt, going to be better than Intel's current offering, as well as be priced incredibly competitively. So, if you can wait a month or two, then we'll likely have many more leaks and information about the new processor line-up in that time period as we get closer to Computex 2019 (May 28th). However, just to be fair, if the current rumors are anything to go by (rumored prices at very bottom of that link), then the new AMD processors might be flying off the shelves and there may be low availability right around the time that they launch, so it could end up being another month or so until you can realistically get your hands on one if you aren't an F5 warrior.

Just something to consider.
