Is there any performance difference between choosing a I7-9700K vs I9-9900K as far as Blue Iris goes, assuming around 1300mp/s? Benchmark tests show them to be equal. Is the hyper threading beneficial for Blue Iris?

Neither of those are CPU model numbers. Did you mean i7-9700K vs i9-9900K? You are looking at the wrong benchmarks (e.g. single-threaded ones) if you think they are equal. Blue Iris does benefit from hyper-threading.
Both will handle 1300 MP/s but the i9-9900K would handle it with more CPU to spare for things like Windows Updates, remote viewing, and for when you want to review multiple clips at once using the timeline control.

Yes, typo.. fixed! The 7900K is $329 and the 9900K is $459. Would you say it’s worth the extra $120? I have a i5-8500 that I’m maxing out now. 40% cpu and adding another camera shoots it up to 100%. Have disabled cameras and enabled the new ones and same results just to make sure it wasn’t the settings.

On the new camera that you’re adding, make sure it’s using «Direct to disc» and not trying to re-encode the stream.
I’m far from being a BI expert, but it’s hard to think that adding just one camera could bump the system up from 40% to 100%.

Moving from i5-8500 to i7-9700K is going to be approximately a 45% increase in processing capability whereas moving to i9-9900K is about a 70% increase (based on cpumark scores). If I was going to do the upgrade, it would be to the i9-9900K for the extra headroom.
Just to give you an idea of how much variability there is in Blue Iris’s CPU demand, my i7-8700K system with 1188 MP/s has the CPU between 50-60% with the local console open at unlimited frame rate on a 4K monitor, or around 26% with the console closed.
So just opening the program to do live viewing is doubling my CPU usage. And this is with the help of a discrete graphics card (if I connect the monitor to an onboard video output, the CPU usage will jump above 80% with the console open!!).

Also make sure your memory is configured in a dual channel arrangement because memory bandwidth can be a limiting factor too.

Yes the settings are the first thing I checked. When I disabled the same model camera and then enabled the new camera, CPU was the same. Re-enabling the original camera causes the CPU to go to 100%. My GPU before the extra camera hovers around 90%, and then when adding the new camera it goes right to 100 along with the CPU. I think the extra GPU utilization is what causes the system to max out.

You can turn off hardware acceleration for one camera at a time, via the camera properties > video tab.
