The X3D chips can't be overclocked, at least not officially. So, it's running at stock. Theoretically, a maximum of 4.5GHz but I think I get just over 4.4, I guess because the cooler isn't keeping it cool enough. The Dark Rock cooler worked fine with my previous cpu, 3900X but with the added cache on the 5800X3D, it's struggling to cope. I tried re-pasting a couple of times but it didn't seem to make any difference. The Arctic AIO has an off-set mounting bracket, which seats the cooling plate more over the 3D V-cache and is supposed to help with keeping the temps down. I'm hoping to knock at least 5 degrees off, maybe 10. From the videos I've seen online, it does look a bit fiddly to mount but it can't be worse than the DR Pro 4 (I hope!). Although it runs a bit hot, the actual performance is fine, pretty smooth, apart from the usual places like flying over dense cities, like London. It's not in the 90's all the time, just occasionally one or more of the cores will peak briefly and then subside. When not running MSFS, it idles at about 50-55 degrees. The 5800X3D was a big step up from the 3900X and I'm hoping the 4090 will give me that final bit of smoothness in demanding locations / scenarios. I think the 7800X3D is about 15-20% faster, on average, depending on the game, than the 5800X3D. At 4K, there won't be much difference between a 7800X3D and a 13900K. The 13900K also runs hot, so that would need a good cooler, too. I think if you just want to use it for flight simulation the AMD chip is the better option. If you needed to do productivity tasks like blender or video editing etc, as well, Intel would be the way to go.

For anyone building a new PC just for flight sim, now, I think this is the way to go. Your parts choices look fine. I would say the X3D chips do run very hot because of the extra cache on top of the die. So, get the best air cooler or AIO you can afford and get a case with good airflow properties (check out Gamers Nexus for case reviews). My 5800X3D regularly peaks in the low 90's when running the sim. I have a dark Rock Pro 4 cooler fitted currently but I have bought an Artic Liquid Freezer II 360 AIO to replace it. For the Power Supply, I went for a Seasonic Vertex GX 1200, as it has one of the new 12VHPWR cables included as standard. I think you will be happy with the performance of the 3090 with the new chip and would only need to consider the 4000 series or higher, if you wanted to get into VR and run it to a good level. I bit the bullet and bought a 4090, which will be fitted along with the AIO and PSU in the next week or two. I've had the parts for a few weeks but have been too bombed out from work to get around to doing the upgrade! Best of luck with your build.

The other place you can check is the manifest.json file in the specific aircraft folder.
