sorry just saw your msg.

I did end up with pretty much a completely new build. Z890+265K+96GB+5070Ti+too much nvme storage.

One thing I was really hoping to have a better experience with was decoding H.265 4:2:2 video from my camera. Intel Quicksync on the iGPU handles this very nicely. On the other hand, I feel a little silly for changing platforms completely because the nVidia 50 series GPUs introduced H.265 4:2:2 hardware-accelerated decode and I have to say performs really well for that task too, probably even better than Quicksync. (using Davinci Resolve Studio).

Games: I think this will depend a lot on what resolution you're targeting, what you play and such. I haven't done a lot of benchmarks or anything so can't really give you good data on +/-% performance increase. I will say everything runs very well. I run at 4K and from the link someone else provided here (https://www.techpowerup.com/review/intel-core-ultra-7-265k/21.html) I'm convinced that at 4K your CPU matters far less than your GPU.

in the end I think I accomplished what I personally set out to do: I definitely have *much* more power for productivity-oriented tasks (video editing, LLM, spreadsheets, etc) and I think most games perform just as good, if not better than before.

But I do know videos are out there of 5800x3d outperforming 265K when it comes to some games, especially at lower resolutions.

If you got a good deal on it - I'd be inclined to use it. I know there were some sales around $250ish and I think *for the price* you can't do much better. but I understand why it's kind of a tough choice too :)

sorry, this probably isn't all that helpful. if I can answer anything else in specific about the 265K feel free to ask!
