I use an AMD 7900rx with an AMD 7950x processor since almost a year with Gnome / Wayland on Arch. No problems up to now. Yes, I am a gamer too.
As others said it depends on the distribution you use.
The hot water pipe to the kitchen is quite long. We have a pipe loop there with a pump. Back in the days we had an ordinary timer that let the pump run at the usual times when there is hot water demand to be expected.
I now use a Zigbee plug for the pump and added a button in the kitchen to start it manually. In addidion HA starts it in the morning and every time when somebody comes home. Another HA automation turns off the pump after 3 minutes and ensures that it does not start again for 30 minutes.
