Is certified hardware necessary for best performance?

I am in the process of upgrading my PC to a bigger, badder, faster version. So far as I could see, all the certified Dell products are laptops. Should I be concerned about this? I'm not running certified hardware now either, but I don't want to spend \$4K and not have a good solution. Note: I am getting a certified GC (Nvidia Quadro RTX4000).

The build I am looking at is a Dell Precision 7920 with 64GB of RAM, 3.2Ghz at 10C, and the above graphics card.
