I have tried overclocking CPU's and GPU's.  I had some good success with CPU overclocks, but never had much success with GPU overclocking.

In my experience, MSFS becomes unstable *very* quickly when the GPU is overclocked, leading to frequent CTDs.

yup this is an issue with msi afterburner when overclocking.  

Depends highly on the Quality of the silicon that you purchased and the power layout of the board. Not every chip has the headroom. If your going to spend money on a card that has a factory overclock you already know you will have higher quality silicon with more headroom than stock so more than likely that chip can be pushed a bit further. More expensive yes but if you know what your doing you wont have any problems. I have overclocked all my gpu's  because i try not to purchase the stock clocked cards.

For example, the present card in my system came with one of the higher factory overclocks of its generation, I routinely run it an additional 250mhz higher on the chip plus  5% higher memory clocks and 15% additional power via the built in overclocking app within the radeon software. Absolutely no issues over the years ive had the card.

In my decades of experience overclocking GPUs I can categorically state this is incorrect, I've seen improvements of up to 20% depending on the Game/Sim when adding an overclock. Racing Sims have benefited me massively from overclocking as I've been able too add higher graphical settings which improve the immersion, so if you do it correctly by thoroughly testing each overclock stage/setting as you go then Yes you can gain something.

Now I'm not sure on the nVidia App, I've always used external programs (MSI Afterburner for example) and in the past MSFS itself never liked overclocks as the Sim would often CTD although IIRC I haven't tried since I got my 3070ti...may be worth a play one day.

Did you read what I wrote ? That OC the graphics card does do almost nothing in P3D and MSFS. 

I did not write about other games and if it made any difference 20 years ago.

Like you I also have decades of experience , but in my case building and configuring Flightsim computers. Not only for myself but many other flightsim enthousiastics…

Been using it for some time no problems.
