The only reason to choose the i9 13900k is if you don't have a graphics card otherwise you are just spending more money for something you will not need (integrated graphics)

That is not the only reason, i have a dedicated Nvidia but still use the integrated graphics card in addition to the nvidia in order to support two more monitors up to six without needing another external GPU, because graphic throughput is not critical in my use case. Only need the nvidia RTX for IA and to support multiple monitors for productivity. Not everybody is a gamer but thanks to gamers we still have access to quality hardware without being a niche thing.

i9 13900KF maybe $30.00 cheaper & 2% faster in certain situations, but I would sacrifice that for the onboard video, (in case my video card dies), and the ECC support. I mean really... at the cost of this chip, you're worried about $30.00?

I prefer as less unnecessary technology as possible on the CPU and mainboard. There was a time when we could decide to purchase mainboards that did not have onboard sound, etc. This is to avoid any conflicts or unneeded usage of resources and one less thing to worry about that could malfunction. So it is not about the price but rather being more in control of what I require in my builds.

30 dollars? There's a 200 dollar difference in price at places like PC case gear where are you looking

Gunther, It is not unnecessary if you do video rendering and can use both GPUs. You get, depending on the external GPU, maybe up to 8-15-20% more performance (from what I could see) with also using the hardware acceleration on the intel GPU on the CPU.

i9 13900KF is cheaper and fits my preference for using an NVIDIA GPU configuration.
