If you mean one cable, that has two connectors on it - that's fine, it's designed to work like this. If you mean only connect one 8pin on the GPU - no. The GPU needs more than that.

Cool. How's it going so far? If you want advice from people here, tell us more information - budget, location, for what use, what are your requirements?

What is that motherboard?

4K as a standard means approximately 4000 pixels wide. 1080p as a standard (and very often used to indicate) means 1920 by 1080 at 16:9 aspect ratio. So I wouldn't say your display is 1080p. Don't confuse the standards/terminology. So I don't understand what the question is now. What is 4K in your mind then? What kind of a display are you looking for?

KitGuru also ran benchmarks and on Intel boards in some tests, the CPU seems to have a slight upper edge, which negates the need for PCI Express Gen4 at this moment. https://www.kitguru.net/components/graphic-cards/dominic-moass/nvidia-rtx-3080-pcie-4-0-vs-3-0-scaling-analysis/all/1/

There is - Samsung CHG90. It is 3840 pixels wide, which is basically 4K.

Nvidia does not have any trade-up programs. I know EVGA has one, if you purchased EVGA card and within 90 days a newer product comes out, then you can step-up.

I can't answer them all for you, I haven't used Samsung devices since Note 3 (mostly because they don't offer Snapdragon variants in EU and Exynos is crap). XDA-Developers (along with some searching on the Internet) might be more helpful for you. From what I remember: - PDA is the build number, CSC is the country-specific code. - TMB is T-Mobile, yes. - No, you don't need to stay with T-Mobile firmware. I am not sure if and how it affects warranty though, if that's something you care about. - Yes, you will get updates, but for the region/carrier that you choose. Not fully sure about upgrade paths - if you are gonna do a clean install, most likely you don't. - Generally, the newer the better. Though in the old days there used to be some differences - sometimes newer firmware did not include all features from the older one. Searching probably gives you more information.

That depends on what you are planning to do with the system (if gaming, what games and at what resolution/FPS, if workstation, what kind of applications) and what's your budget.

It's fine. Batteries don't go bad in a year without use.

https://www.sammobile.com/samsung/galaxy-note9/firmware/#SM-N960U It's probably T-Mobile, that hasn't released the updates to the public. The link above contains the firmwares released for your phone. You may have to do a clean install, but you can install a newer one from there.

You can use pass or KeePass or some other tool and store the password database wherever you want. Actual password manager can bring certain benefits over just storing passwords in an encrypted format. For example automatic password generation tools based on your requirements, copy passwords without exposing them, browser integrations to avoid having to copy/type them, additional checks to notify you of reused or leaked passwords (using HIBP or similar), audited code, cross-platform compatibility etc. KeePass also has the option to require a password + a keyfile. KeePassX supports YubiKey in addition to the previous methods. One thing is reliability indeed - flash drives do not have very long life in terms of write capacity. Having multiple ones requires you to keep them all in sync, which is not very convenient. Other concern is where are you planning to use it - do you need mobile device support? How much do you move and need to carry the stick around? Do you use unknown devices or do you only connect it to known devices? If the former, how are you storing/encrypting the contents of the drive? Do you expose them all at once or all separately? Are any passwords/keys going to be stored in memory? It all comes down to your threat model - what are you protecting and from who? Are you a target and for who - who are you worried about? Random script kiddies or national/government level hackers? It's a matter of security vs convenience - where is the ideal balance for you. And as said above, always think ahead to not lock yourself out. Always use multi-factor authentication - you can secure your passwords, but if it's the service fails (data leak, vulnerability, social engineering), it won't be any help. I have used KeePass for years and have not had issues with it. I prefer having more control of the database than the online services offer. I have the database file in my personal/self-hosted cloud.

If you can wait, RTX 3070 should have about the same or slightly better performance compared to 2080Ti, while coming out cheaper (starting at 499). We haven't seen benchmarks yet though, so can't say any certain numbers.

I'd go Ryzen at this budget - you will get more performance for the money.

HDMI ports have versions. HDMI cables have different "types". They use the same physical port, but you will be limited by the lowest port version or cable type, whichever is worse. From Wikipedia: So if the cable is very old/bad quality, it might simply not be enough for 4K. OP doesn't mention what resolution the Dell monitor is, so it could be working fine at 1080p, but is lacking for 4K (especially if it a newer LG TV, which supports 120Hz).
