How common is DPC Latency when using an Nvidia GPU, and AMD CPU?

I'm building a PC for music production, and was planning on running a AMD 9950x CPU, alongside a Gigabyte GAMING OC GeForce RTX 5060 Ti 16 GB GPU, and ASUS X870E Creator motherboard. Plus 128GB RAM and good SSD storage. 

I will be using Ableton and recording with 1-2 microphones at a time. Maybe sometimes up to 3 or 4. 

I am hearing about DPC Latency when combining a NVidia GPU with an AMD CPU. 

Though I'm not sure if this is a rare occurance... and worth the risk of getting a NVidia GPU. 

... Or if it's a near-certainty it will happen, and I should definitely go with the Radeon RX 9060 XT GPU?

(I am trying to build the PC for quietness, and hear the Gigabyte 5060 Ti is quieter. I was hoping to go with that one for it's performance, and quietness... but just not sure how big of an issue DPC Latency will be down the line).

If you're building purely for music production, why a gaming GPU ?

7950X + GTX1070 = no problems. at. all. in audio.
Your mileage may vary. This is old card.

DPC latency does not directly lead to audio latency or stutter.

Some work stuff I do requires a GPU. CAD etc. Might also be running local LLM models in the future (not music related)

I got slightly reduced DPC latency when going from a GeForce RTX 3060 Ti to a Radeon RX 9070 XT. However the DPC was very low with the Nvidia card too, nowhere near enough to cause any issues.
Take a single oscillator, producing a drone. Send it to the wave shaper, altering the tone.
This can be a triangle, Sawtooth or a square. Modulate the pulse width, nobody will care
