Here is what I just researched.  You may see my choices relevant to your planned upgrades. Just spec'd out a new system over the past two days and now waiting for the components.  Did a good deal of research and used https://pcpartpicker.com/products/ to pick choices.  Got some great guidance here and even better from the local builder I am using. My builder moved me from a Corsair cooler to the NZXT saying from experience it is better. I am paying the local shop $320 to build, install the OS, and bench test.  You mention some of the components I selected.  Here is the list as I ordered at Amazon:

$     134.99	Case	Corsair 5000D Airflow Case
$       44.97	Fans	Corsair SP120 Elite, 120mm PWM Hydraulic Bearing Case Fan (3)
$         8.49	Splitter	Cable Matters 2-Pack 3 Way 4 Pin PWM Fan Splitter Cable 12 Inches
$     366.80	CPU	AMD Ryzen 7 7800X3D
$     226.42	MOBO	MSI MAG B650 Tomahawk WiFi AMD B650 Socket AM5 ATX
$  1,069.99	GPU	ASUS NVIDIA GeForce RTX 4080 Super TUF Gaming OC
$     114.99	RAM	CORSAIR Vengeance DDR5 RAM 32GB (2x16GB) 6000MHz CL30 AMD Expo iCUE Compatible
$     169.00	PSU	Corsair RM850x 850 Watt 80 Plus Gold ATX Fully Modular Power Supply
$     179.99	Cooling	NZXT 360mm AIO CPU Liquid Cooler
$         8.99	Paste	ARCTIC MX-6 (4 g, incl. 6 MX Cleaner) - Ultimate Performance Thermal Paste
$       99.20	SSD 1	SAMSUNG 970 EVO Plus SSD 1TB NVMe M.2
$     319.99	SSD 2	SAMSUNG 990 PRO SSD 4TB PCIe 4.0 M.2
$       79.99		Corsair Vertical Mount  Extension Cable
$       14.39	Stand	Adjustable Mobile CPU Stand, Ventilated Computer Tower Stand

I think he made excellent hardware choices for the purposes of the present sim and if he has any questions or need any assistance ill be glad to try to help.

Sorry, I thought that upgrade to newer cpus and PCI5 graphics cards was only possible with 670E motherboards

No prob .. Trust me if there was any tangible performance gains to be had going with the X670 i would have been first in line myself !

Your parts are similar to what I built last year, except I didn't go with an MSI board, although I could have, I like their stuff.  That thing should be amazing in MSFS.

Stand

Adjustable Mobile CPU Stand, Ventilated Computer Tower Stand

Ventilated?  Is this typical stand with casters, but then are fans mounted on it?   That's a low price even for a regular stand.  What is this one exactly?

It is only a simple cart to move the system into and out of position when needed.  It need not stay in place.  It does have ventilation openings.  The bottom of my case I believe feeds only the PSU.

Lossless Scaling is a little tool you get for some bucks on Steam that doubles, triplesfor quadruples your FPS. Properly set up, you get a very smooth experience at the cost of some artefacts. No longer time testing experience here, so I do not know if the tool works for an e.g. 4h simming session. 

AutoFPS lets 

My biggest advice would be: try those tools right now, it might make buying new hardware even obsolete 😉

This is good advice. Try Lossless scaling and AutoFPS first.

Are you using both simultaneously?

 I very much approve the core components for your upgrade (Check signature)

The components play together very well and can be pushed without too much effort (PBO/Memory timings)

You may want to temper your expectations just a tad if you plan to max everything out including add on traffic ( such as AIG @100%) and want to fly into a major international airport in a resource heavy aircraft. We aren't quite there yet unless frame generation or auto fps is involved but its pretty darned close.

I also see that you are looking to run the sim at 4k .. that will be your new bottleneck so you can either wait to see what NVIDIA comes up with in a few months or go with a 4080 Super/4090 if your budget allows.

 

Thank you! I do have the expectation to get better smoothness and less stutters in airports like Heathrow, with traffic (I have been using FSLTL mainly, but considering a payware option just not sure which to get yet) and cloudy/rainy weather (I use REX Weather Force). But with regards to the monitor I think I will need to sacrifice resolution for the higher refresh rates I am considering for other competitive games like CounterStrike 2. I will post in a moment what is available here for some opinions.

If you're building the rig for MSFS then the AMD X3D CPUs are currently considered the best performers due to their large cache. Bear in mind that MSFS 2024 is only months away and might turn the table over... There are also issues with voltage damage on Intel's top end CPU's that are putting people off.

 

Ok thank you for that! The Intel damage is something I was concerned about.

My CPU temps (PBO enabled) while the sim is running floats in the low 50c and the occasional 60c but good cpu coolers and the choice of cpu thermal paste will play a role in the results that you may get.  Idle is 41c to 44c

Thermal limit is 90c so nowhere near it.

When I fly on my current rig with heavy weather at complex airports and traffic I get CPU temperatures of between 80-90. In basic airports with clear weather and little traffic I get about 60-70. I have good thermal paste (Grizzly), liquid cooler and I keep my PC well maintained and clean (physically and software wise).
