So i'm running a non OC'd i7 8700K and i'm thinking of going to a 9700K.

My MOBO is an MSI Z370 PC Pro, I think I can still use the mobo with the 9700K, but I thought I would check with you guys first just to be sure.

Also, the MOBO has a BIOS feature called "OC Genie", essentially a one click solution that runs the turbo clock of the 8700K up from the stock 4.7 ghz to 4.8 ghz, it does work, and i've verified it with both AIDA 64 and CPUID HW Monitor.

The 9700K has a turbo clock of 4.9 ghz, so do you guys think I might be able to squeeze a little more out of it with this OC Genie thing in my BIOS....??

Any info is sincerely appreciated.

So, let's say OC Genie lets you run up the 9700k to 5.0GHz. That's 200Mhz faster than what you can run your 8700k at. In other words, a 4.2% CPU clock speed increase, which translates to LESS than 4.2% overall gaming performance increase.

That is an extremely terrible performance-gain-per-dollar investment. Skip the upgrade.

If you have an 8700K now, then getting a 9700K would be a waste of money, they are equal in performance.

Thanks for the replies gents...

So what are my options in terms of a CPU upgrade that might be worth the expense..??

Overclocking (aside from the OC Genie option) and/or delidding just isn't something I am comfortable with or experienced enough to attempt, and it may also require a better cooling solution as well, and I just don't want to go down that road at this time.

Fair enough, but I see you're running a 9900K, why wouldn't something like that be a worthwhile investment for me..??

FWIW, the "game" i'm using is Lockheed Martin's Prepar3d... aka, P3D v4.4, it's a flight simulator and is very CPU clock cycles dependent.

It generally runs quite well with my GTX 1080Ti and the 8700K, but as they continue to update the program, it places ever increasing demands on the hardware, and i'm just trying to "look ahead" so to speak.

Not unless you upgrade the MB, that's a budget Z370 MB, you would kill it if you put a 9900K in it.

Very weak VRMS.

Thanks, your advice is much appreciated... I had that happen once before, so I certainly don't want to repeat that mistake again...

Got any suggestions on a mobo pick for an MSI board that would be a good choice for a potential 9900K upgrade..??

BTW, my power supply is a Corsair 650W "gold", would that need to be upgraded as well, just to be safe..??

In a nutshell... Best performance in the flight simulation I currently use, which is Lockheed Martin's Prepar3d... AKA P3D v4.4

FWIW, the requirements to run this smoothly and with good frame rates, with a variety of high end add on airports, scenery, and aircraft, is very much different than the typical FPS shooter or Racing game...

This isn't your garden variety "game" where you might just add some "skins" or a mod or two, it's way more complex than that....

I get the impression that there aren't a ton of P3D users around here, so the specific needs and requirements for "best performance" in P3D v4.4 are probably a little outside the scope of the knowledge base here, which is completely understandable, and I sincerely appreciate all the replies and suggestions...

Ah, see - that helps. While I don't know a darn thing about P3D, I was thinking initially that this was going in the wrong direction for gaming.

Though, it couldn't help to know how much demand this puts on the CPU vs the GPU. Come to think of it, what's your GPU and what's the resolution/refresh of your monitor? Though I guess maximum FPS isn't really a need/goal here.

It might help to see what the load on your existing CPU is like when running this, though, overall as well as on the individual cores. I wonder if this really requires more threads rather than faster single-thread performance... but I have no idea.

EDIT: stumbled across these links as well, though, based on what's implied, it seems like you're well above the recommended CPU requirements, so, maybe GPU? Also, if you're not running it off an SSD, seems like that'd be strongly recommended (I guess because a LOT of visual data has to be loaded in)

Thanks King, yes, you are absolutely correct, i'm well above the recommended requirements for P3D, but that's for the base program, when you start adding complex add on scenery, airports, and aircraft etc., it's a game changer (no pun intended), and therein lies the problem.

My setup works well enough for the time being, but as P3D continues to evolve, not only the base program itself, but the complex add on's as well, the need for more "horsepower under the hood" keeps growing, and i'm just trying to stay "ahead of the game" so to speak.

Oh, and BTW... I do run this from an M2 SSD, and yes, that helps a lot with loading the intensely detailed add on scenery etc. Thanks again...

Yeah, and with some of the add-on scenery, I wonder how much extra stress that puts on the GPU vs the CPU.

It couldn't hurt to run a hardware monitoring program that will track CPU utilization individually for each CPU core/thread, as well as GPU utilization, on a graph over time. That'll really help nail down exactly where anything falls short.
