I buy Nvidia myself because of the headache free process. The same goes for Intel when it comes to CPUs.
It seems that “headache free” also depends on your operating system. For the past couple of years I’ve only heard on Linux that AMD is by far the better choice because the driver is entirely open source, unlike nVidia, where only a portion of it is open source. Also, Wayland (the alternative to X.org, which is finally slowly becoming mainstream) seems to work better on AMD.
(I’ve only had issues with an nVidia card once, and that was with the GTX 560 Ti, where a bug in a newer driver affected this type of card specifically, and it took a year to resolve.)
In terms of the CPU, I’d like something with as many P-cores as possible (and no electronic cores), and at the moment AMD seems to be the better option; Although I regret that they took the CPU temperature as a maximum instead of the power consumption, in the case of the 7950x.
For me, a new computer is planned after the release of Debian 12. This could be an AMD system, with an AMD CPU, an AMD card, and an AMD chipset on the motherboard. That would be a huge leap of faith, because with the exception of 1x (in 2001, and that experience was bad) I’ve always had only Intel + nVidia.
