I would go with this, the x is also fine.

I agree. MSI or Corsair

All will do equally well. You won't be able to tell them apart really.
Personaly I would go with the RM1000x or MSI MPG A1000G.

A quality 850w will be plenty.  The 14700k can draw 250w ( This never happens unless you do a 100% stress test ) and the RTX 4080 draws 320w.
Lets say you run at 100% on CPU and GPU you are looking at 570w, Fans use around 3-5w and RAM uses around 3-4w per 8GB, M.2 SSD's around 10w when writing.
So lets say 620w for 100% full system load.  850w is more than plenty for this system. 1300w is 2x what you actually need.
If you want to be 'extra safe' Get a 1000w. 1300w is just overkill.
The RM850x and RM1000x from Corsair are really good, I exlusively use the RMi/RMx series in all my builds.

Why not an ATX3.0 PSU? https://pcpartpicker.com/product/4XsV3C/be-quiet-pure-power-12-m-850-w-80-gold-certified-fully-modular-atx-power-supply-bn505 is cheap and good.
Other decent ATX3.0 units, superior to the be quiet! and cheaper than a RM1000x.

The Gigabyte cards have had a lot of issues with the PCB cracking near the PCIE slot. This might be fixed / reinforced on the Super cards however.
I own the MSI Gaming X Trio and its great, the ventus model is also very good.

In terms of PSU's, Here are your choices. My preference goes to BeQuiet!

For GPU - MSI RTX 4080 16GB VENTUS 3X is a good option. Have got one and it runs very cool.

PSU questions aside. I just want to mention that I absolutely love my RTX 4080. I bought it on release back in 2022 and I haven't regret it at all, even though the price to performance might not be the best its a damn fast card!  Its been stable, quiet, easily overclockable and an absolute dream to game on. I love this thing.
What RTX 4080 models have you been looking at?

Also do consider the 14700KF instead if you have no uses of an iGPU. It would be the better choice unless you do need the iGPU for something.

yeah the rm1000x would be good, has plenty of warranty years and the price is not bad either.

The RM1000x would be my choice. It comes with 10 year warranty and is a very reliable unit. 
I use the RM750i/x in my system with a 4080 and the PSU has been working well since I bought it in 2016 and have used the RMx series in over 20 builds as I trust its reliability.

you can limit fps using nvidia profile inspector:

therefore reducing GPU load.

All phones are horrible. I'd suggest avoiding them entirely.

Definitely the htc vive because, air cooling is often better for silent operation and you have a lot more maintenance costs and labor with watercooling.

What game? I imagine it's a little older if it doesn't have more options.  If it's not too intensive, I recommend just rendering it in 1440p or 4k, your 970 should handle older games fine at that resolution.  If you're interested, you can find the guide here.
 
As for Nvidia inspector, I'm sorry, I haven't used it. But if the in game option is only on or off, I imagine it's only 2xAA, and if you can set the value higher than that in inspector than you should get better results. 

i use foxit reader, my brother uses sumatra reader, those are more light PDF readers

haha im clueless here... when something like this happens, I usually back up my computer to an external 2TB seagate HDD and reset it. then i reinstall windows and its fixed. lel

im sorry, i dont know how that appeared, i will remove it right away

Real Silent is good: http://www.amazon.com/dp/B001AZHRYG/?tag=pcpapi-20

Nope, you've got the steps correct
 
Enjoy your new GPU

All correct, remember to shutdown computer when installing the GPU.

My recommendation is to use DDU to uninstall drivers, everything else is correct

Logitech G710 or G710+ 

dlls are not united states dollars???
