First up, in current market just about anybody for any reasonable application is going to have a hard time arguing against going AMD. The Zen 2 architecture is offering a lot of performance at a great value and aside from Intel favoring edge cases in specific software or scenarios its pretty much the go to. For your uses 8 cores / 16 threads should be more than enough. We pair our CPU with ASRock's Taichi X570. The Taichi line has been making a great name for itself the last few generations and I use the X299 version of it in my current PC. Its solid, has plenty of features, and more than adequate power delivery should you decide to try your hand at some overclocking.
With that we move to the RAM and CPU cooler. On our RAM we have a very nice G.Skill kit sporting true 16 latency rather than the 16-18-18 crap some vendors are trying to pull and still call CL16, at a healthy 3600mhz. Zen 2 likes faster RAM and this should balance that out very well. To cool our CPU we have the Be Quiet Dark Rock Pro 4. Not a cheap cooler by any means but it fits the bill in just about every way. Its quiet, it has more than enough cooling to keep our CPU very chilly, and the black finish matches the general look of the rest of the build. I also added on some Thermal Grizzly compound as its the best on market and will possibly net you another few degrees in CPU temps.
For storage, the tried and true 970 EVO Plus will suit us just fine, in a high 2TB capacity. This will run your OS and let you install plenty of games with room to spare. Should you need some additional space for media or other things, we back this up with a WD Blue SSD. I'm personally starting to shift away from mechanical storage entirely, and I think I'd recommend you do the same if you're building anytime soon. The cost is definitely higher but unless we're going to build an actual RAID I have a hard time making an argument other than price for mechanical storage at this juncture. On the subject of NVME PCIE Gen4 should you wonder about it, I'm not convinced its going to make much of a difference for you or most people right now. If Samsung had their Gen4 products out I might recommend one, but depending on price differential, possibly not. I don't think its anything to hold the build up over.
You said you wanted a 2080Ti, and a 2080Ti it is. There isn't much to consider on the various offerings besides their included cooler, and I think a 3 fan windforce should do you fine.
To house this build I selected a Fractal Define S2 Blackout. If this isn't to your taste you're free to select something else. This is the case I use, I found it a pleasure to build in, and it fits plenty of fans. On the subject of fans, the case includes its own fan hub/controller and into it I recommend you place all these nice Corsair Mag Lev Pro 140mm fans. I have mine whisper quiet when idling and only moderately less quiet under load. You'll have to tune them to achieve the same but it took me maybe all of an hour to tune them exactly as I like them.
The powersupply is a SeaSonic. I don't think I should have to say more than that.
Finally, I selected you a 27" 1440p IPS monitor, clocking in at a generous 165hz. There are cheaper offerings than this one but for a confirmed GSYNC rather than the iffy 'GSYNC compatible' I personally don't mind the premium. You can take the gamble if you want however, or some shopping around outside PCPP might yield some results as well. As good of a tool as PCPP is, I think monitors are one of the few areas where I feel they aren't as on the mark with having a very complete picture of available products, so some legwork might be beneficial here. I'll review any monitor you find to see if its up to the task.
