If you mainly mix or do post production then computers today have more than enough power. But for tracking even today with Apple Silicon the HDX card is still king. No buffer settings. If you have a large mix and want to track into it you get zero latency especially with Pro Tools Hybrid Option. I like to record my guitar direct and use Amp Modelers in Pro Tools WHILE I am recording. With HDX its zero latency using the DSP plugins. I never could have done this before and would have to record via some external modeler and then re-amp later etc. With HDX it opened up so many doors. Owning many systems and state of the art computers and interfaces I have never gotten reliable zero latency. I purchased my HDX in 2023 after trying Apple Silcon and every other option to get low latency. HDX was the best investment in a long time. Do not let anyone convince you DSP is dead and you can do it in the box. Yes for post and mixing but not for tracking.

I've been using HDX for years. It just works. I added a second card to have more horsepower and tracks. Sure there is the argument that we should just be allowed to push the software to fail, but I think that's a waste of time. I want to feel confident that when I turn the system on it's gonna work. I've sat there before, turning off tracks. Freezing tracks. Asking my client to wait while I tinkered with the system. It's a waste of time and kills creativity. There is a reason why Pro Tools is the professional choice.
