I’ve lost count of the amount of times I’ve looked into Linux and decided against it. Looks like too many headaches for a codger like me - I just want the easy life for my retirement

then I recomend prebuilt next time with preinstalled stuff

My parts are slowly arriving for my build. One of my last parts is my video card, what how much RAM can I get away with? Is 12 GBs RAM reasonable?

The most amount you can get away with.

Every upgrade’s excitement at new abilities and performance is tempered with the frustrations, anger, and sheer WTF-ness of dealing with drivers, BIOS, cable routing, and the Magical Wonders of Windows.

Well that’s roughly what there was on my 2080Ti and that didn’t have many issues, so I’d think it would be okay.
I can only answer that with another question: How many pixels are you pushing?
EDIT: I can say more:
For 1440p or less, 12GB is fine.
For higher, I would try to get 16GB. But it depends on the card. The RTX 2000 and especially RTX 3000 series have huge memory bandwidth, so they can do more with the GBs than the RX 6000 and the modern RX 7000 and RTX 4000 series, which have lower bandwidth but use a bigger cache.
My RTX 3080 is doing great still with only 10GB, pushing 3000x3000 pixels in VR

Well, to add to it all I can’t sign in to Oculus/Meta Home on PC - I keep my passwords in a secure archive separate from my PC and I know it’s correct, but Home is saying it isn’t.
I go to Meta’s VR site and change the password - jumping through the confirmation hoops repeatedly. then I go back and try to log in with the details I have only just confirmed are accurate at my Meta account and it still says it’s wrong!
Good example of why I won’t bother with another headset from them. If you add in the fact that just trying to get in touch with support is frustration in itself. The old pigeon-holing crap yet again. Of course, Home isn’t one of their little slots, so you can’t choose that - or accounts, only VR hardware.
The only VR apps worth bothering with are the ones on my PC. At this rate, I’ll be dumping the Quest 2 as well. Maybe they’re just peed off because i closed my FB account! 
*finally managed it!
If you are typing all these passwords on your new pc and they say they’re wrong perhaps something is wrong with your keyboard/language settings?
Thanks for the information gents. I’ll see if I can squeeze out at least 16 GBs out of my budget

One more thing: try not to focus exclusively on VRAM. Nvidia abuses this view by offering 16GB versions of 8GB cards at HUGE markup. Performance difference is negligible. Just get a card that makes sense for your resolution:
1080p: RX 6700 XT, RTX 3070, RX 7700 XT or RTX 4060
1440p: consider RX 6800 XT, 7800 XT, RTX 3070, 3080
4K: consider RX 7900 XT, RTX 3080 (Ti), 3090, 4070
VR: same as 4K or higher
Do not buy RTX 4060 16GB, it’s terrible value for money

Thankfully after the initial frustrations (mostly expected) everything is going well. VR now set up and ready to go and all important stuff sorted.
Now come the flight sims and Elite. I’ve left all 3 sims on the separate hard drives and will just rearrange the configs or point the installers to the installed folders. Hopefully this won’t entail too much updating - I did the same with my Steam games and in the event, somehow all the workshop content was lost (must have been on my C drive - knew I would forget something) and so I ended up having to download huge amounts for ArmA3 and racing sims like rF2. Still, all done yesterday
oh, before I go - I was looking at the new SteamVR UI panel and found some rather interesting things. One was that it says my graphics card is an AMD Radeon, even though it’s an RTX4080 - is this normal?
Then it also says my VRAM is a mere 512MB and I’m worried about what effect this may have if programs look at this info for automatic settings etc.
The only other current concern is the BIOS. I’ve had intel processores since the Core2Duo days and am not used to AMD processes and nomenclature, so I am almost completely lost with the BIOS and the section in the manual just says “don’t mess if you’re not an expert”. Very helpful - I have mobo manuals from years gone that explain every feature of the BIOS in detail…
Now, on to those flight sims…

What is your monitor plugged into?
The Ryzen 7000 CPUs come with integrated GPUs. This sounds like an integrated GPU.
Make sure your monitors are plugged into the dedicated GPU, the RTX 4080 in your case.

As for BIOS settings, I recently found out that Halo: Infinite has a problem with resizable BAR, which is enabled by default. Most games should get a small performance boost from it, but if you’re worried about compatibility, you could disable it…
Other things I did in my BIOS are:
- Set reasonable fan curves for case fans based on the temperature at the PCIEx16 slot (GPU), instead of the default that has all fans set too high by default and spool up and down with CPU temp.
- Disable the TPM thingy so Windows would stop bothering me about Windows 11 upgrades. Though it might be time to bite the bullet and upgrade to 11, with Windows 12 coming next year.
- You probably want to set PBO power option to “motherboard” (if that works the same as on B550), other than that, overclocking is not really worth it.

Sucking eggs here! Sorry mate, but that was a bit below the stomach!
Thanks for the BIOS tips - I have a separate controller for my fans (hardware) and have had no issues with temps - in fact they are surprisingly low all the time (6 fans fitted and a good front>rear flow).
I was already aware of the TPM thing - looked a few days ago for my previous PC and after enabling it on that, watched some Win11 vids and reviews, then went back and disabled it again! I’m hoping to miss out 11.
PBO thing I’ll check. I didn’t want to overclock myself manually - just wanted to ensure that the built-in boost etc were enabled, which is hard to recognise with this AMD CPU - was easy with intel, cos it showed both speeds and the expected speeds if I changed settings - this doesn’t seem to do that.

Sorry to keep budging in here, but what PSU you all running with?
Ta
Corsair HX850
This also highly depends what resolution and GPU you are using. Why don’t you start your own thread with the details about your needs and budget in the first post?
Last time I looked into it, PSUs from the same “line” with a different Wattage but otherwise identical name and brand were completely different units from different factories with different quality levels.
So don’t think “I’ll just go Corsair” since the brand has very little to do with what’s on the inside. They only come into the picture if the PSU breaks, which it should not.
This is an open ranking with tons of people who contributed to it and hours of research:
I’m using a Corsair RM850 (2019 model) btw and it buzzes on standby. I had it replaced for that reason but the second one buzzes just the same.
