If the only difference is the Integrated graphics, save the money and invest in a better GPU.

K = IGpu backup, for no Dedicated GPU system, more expensive. KF = no IGpu backup, heating 8 degrees less(great for O/C), 2% faster, cheaper price. make your choice (for gaming a KF . I choose 12700kf almost powerful of a 12900k for gaming and a lot cheaper! )

You're drawing loads of wattage from the lighting system you likely chose so why complain about iGPU wattage. If you're using it for mining then you eat about 1MW for less than $200, which is probably worth it if you own land at the 10 ft mark. Anyway, it's just watts that make up the difference.

Since both CPUs are virtually identical in specs with the exception of the added iGPU in the K version and then maybe 60 bucks +- more for the K version, consider you cruising along playing your favorite game or working on an important report for work or school and your screen(s) goes black. With the KF version, you are dead in the water. You may not have the ability to troubleshoot the issue unless you have a spare GPU laying around. Having the iGPU of the K version and not using it because you have a dedicated GPU is just a safety net worth the extra money in case you run into the worst-case scenario. Yes, the iGPU may use a very small amount of power even when not in use, but you can't deny that having that safety net available when tshtf is just plain good planning and could save you from heartache... just unplug your monitor(s) from your GPU and plug into the iGPU slots and you're on your way to figuring out what went wrong or finishing that report. You may not get a good performance for gaming with the iGPU but you sure could finish that report for work/school with the iGPU. Saving a few bucks always sounds like a good thing, but seriously consider what you would do if something failed.

You use that rig for gaming 99% of the time. Your rig is drawing extra power, but more importantly, generates more heat. Overheating hardware can cause game lockups, crashes, and performance issues such as low FPS and stuttering. not so nice to have no matter what you use a video card for in my opinion. You should have bought the KF, you would not get problems with it, and the chance for problems is higher for the K to begin with. I've actually had this happen on a pc that also has a native card on it. when your main card breaks, you are not worried about writing a school report, you don't want to use that downgraded card, and you are ordering a new card asap ( you probably get it the same day your card breaks if possible). Another negative, on a K card you must still finish the report. If the video card on a KF board fails you can call your boss, and say your graphics card failed and can't finish the report. he might understand u need some extra time, maybe help you pay for a new card?

iGPU will for sure add some temp when active (even not in use)

I second the importance of an IGU. 1. For debugging whilst building a system 2. Ability to just run without an external video card 3. Ability to debug crashed ext V-card, w.o IGU you're totally dead.

IGP would only be useful in machines without dedicated GPU. However, one important thing to consider is the price difference between the 2.

Is there any reason in the world I would want to pay more for the one with integrated graphics? I am already running an MSI 3080Ti.

Virtualization with passthrough. Might not be useful for every one but it's still a super feature for many of us :)

The main reason is for troubleshooting a GPU. If the GF card goes down you would not have any way to use the system. I leave my IG graphics off in the BIOS and turn them on when having issues with monitors, cables, or GF cards to use as a standard for comparison.

Good call on the KF, bad choice on the prebuilt desktop. Gotta optimize for thermal control when your case is coming from Alienware 'cause you just know they're not going to give you big fans or healthy ventilation. And why should they? Glass looks nicer, and the people who know why glass is a poop material for their box would never buy an AW anyway.
