I would like to upgrade my processor
I have I7-8700K on a Z370 mortal mobo
My question is :if I buy a I9-9900K would that be a big performance? or is it the not worth to do such a investment (550 euro). I only use it for FSX se.
looking forward hearing from you
The comp shop has no idea because they havenot experience with flightsim.

In the right hands you might get a slight bump in performance with I9-9900K over I7-8700K. But FSX is dependent on single core performance and despite the I9-9900K having 8 cores over the 6 of the I7-8700K there will likely be no discernible difference at all unless you really know what you are doing. If I where you I would stick with the i7 8700K and unless Intel's Next offering includes major improvement in single core your system will be current for the next few years. My opinion would be to stick with what you have. With FSX the best way to get better performance is OS optimization and Overclocking if you haven't already done that.

The only reason such an upgrade would make "sense" would be the unlikely situation that you do not overclock although you have a -K processor from Intel. By default, the single-core turbo of the 8700K is 4.7GHz while the one of the 9900K is 5.0GHz.
Then, due to the newer architecture you might also gain some percents in performance.
BUT: even if 100% of your theoretical performance gain would be translated into FPS, the max you can get is maybe around 7-10% (6.4% due to the clock increase, some 1-4% due to the newer architecture). Now you can do the maths yourself: if you now get 20FPS, you might get 22FPS. If you now get 30FPS, you might get 33FPS. Whether or not such an increase in FPS is worth 550€, is finally your decision...
Rather go with Avidean's tipps and try to optimize the performance of the sim itself. And forget about the FPS numbers, the aim you have is a smooth sim, not a high-FPS-number sim. IF you then still think that you could need a boost, overclock this 8700K to 5.0GHz and you will be perfectly fine ;-)

One more vote for staying with your 8700K

Assuming you already have a 1080 (with or without TI) and you are moving to DDR4 4200 @ C17-17-17 and will run the 9x proc @ 5.1-5.2GHz, its not worth the price to change.
Even then this is FSX(se) there is no such thing as "big performance difference" unless you are not overclocked at all right now and will overclock the 9x proc along with running high end DDR4 memory, and, the video card is not a decent 10 series. Replacing it all you would see a difference but not with just the processor.
You are simply dealing with the old sim, addon developers who stuff too much into their products and users who push too much because they cant stop increasing the load on the system.

I always hate saying "me too" but, in this case, it's a no brainer. Not worth the cost.

I have 8700 without the k (I made a mistake)  oclocked to 4.4 . I dont have the knowledge to oc further.
the 1080TI runs well but fsx dont use a lot of the G card only 10-20%.
afterall I am glad to have this imput from you so it will save me money and will not disappointed afterwards.

I dont know what I have for memory but it read 2400 mhz and it is 16 gb.
is that sufficient? because nick mentioned 4200 ddr.
does it mean that i can increase it for a better result?

Don't waste your money..  reduce the settings or remove the heavy hitting addons instead

Based on the info you provided the only thing I would consider is selling the i7 8700 if you can and replacing it with an i7 8700K or i7 8086K. I personally bought a used one. Best to go with Nicks advice. He is the Guru!

No reason to do that...  he is already at 4.4 on a 1080Ti and has a processor capable of doing 4.8-5.0
If he isn't a avid overclocker and cant get that chip to 4.8-5.0 as others have done  AND KNOW he is stable, replacing the processor isn't going to do squat.
He can get just about the same result (a better result in his sim) by having a professional overclock that chip another 400-500MHz for him as long as they know what they are doing and they test the cooling and the stability properly.
So at this point that's his best option.
Or stop the scenery nonsense, one of the two.
