Nevermind the CPU part. I was just wondering if you're experiencing the Intel stability issues.
Have you tried monitoring your GPU behaviour? Clocks, temperature, voltages, power usage, VRAM usage? Anythig out of ordinary there?
Sounds like you have the same issue I had on my laptop. By default my BT was as "non-discoverable" and there was no option in the settings anywhere to make it discoverable and at the same time Live USB boot worked fine. So while I could find the devices I wanted to connect to my laptop, they couldn't because they couldn't se my laptop.
I had to install "blueman" where I can enable discoverability and connect devices.
Yep, CL is quite meaningless and the secondary timings will matter a lot more especially if these are dual rank sticks so get the faster one (3600 C18).
Easiest and also fastest way to do it is with FFMPEG.
Just install FFMPEG and then convert it with this command:
ffmpeg -i input.mov -c copy output.mp4
for example
ffmpeg -i C:/ProgramFiles/video.mov -c copy C:/ProgramFiles/video.mp4
If you do CPU rendering for 3D applications then the Intel CPU will be faster but I'm assuming for 3D modeling you'll use your GPU most of the time so either CPU will be barely used... in which case the 7800X3D is a better gaming CPU.
I have glossy ntb with OLED and even in pitch black you can see mirror of your keyboard backlight on the screen but if you disable it and watch movies it's amazing.
