Sorry, but the speed of your broadband is irrelevant. You can show the resolution and format of YouTube videos with: youtube-dl -F http://www.youtube.com/watch?v=US3Px2sePWk (package is net-misc/youtube-dl) Decide whether or not you need a new PC and make a new post - UEFI/secureboot is irrelevant to poor YouTube performance. Stroller.
