Isn’t this better than trying to make it so that you never click off YouTube, the way it works if you are logged in? I would much rather have no recommendations than have an algorithm give me recommendations with the express purpose of maximising ad revenue extraction from me
Filesystem doesn’t matter hugely but as the other user said, ext4 will be the fastest anyway (possibly xfs, not sure how ext4 and xfs compare). CoW filesystems like btrfs are slower, though most people don’t notice a significant difference. People use CoW filesystems for other features like self-healing ability and backups.
I would strongly recommend getting an AMD card. As the other user says, AMD’s drivers are fully FOSS and work well with Linux. Nvidia has a bad reputation with Linux and especially Wayland, though these days it’s mostly usable, but IME is still prone to breakage upon updates. IME AMD GPUs “just work”.
