I don't intend to sound harsh or whatever, but I really don't think this content works on your channel. Your viewerbase (based off of the content you put out, and the people I see comment) is far passed tutorials such as this, and to be quite honest, if someone did need to learn how to install a graphics card, the kinks of doing so, etc, they can search YouTube, click the first link (a tutorial made over 6 years ago with much of the same information as in your most recent video) watch that video, and learn everything they need to know. I can't really agree with having daily uploads of crazy, high level PC builds, insane servers, high end laptops, custom mods, things like Scrapyard Wars, etc., and a random basic noob tutorial out of the blue. I haven't really seen many people ask for it. I mean, sure, there are probably a few that have, but I doubt the number was large enough to justify this video (which, as of right now, is universally seen as just another, lazy, filler episode).
Now, just to clarify, I did say "on your channel" this does NOT mean that I don't want LMG to make basic beginner tutorials on another channel, but I don't really think that it works in the way you're releasing it. Keep in mind, that 2 years ago, you did have an incredibly beginner friendly video, here, which in my opinion, is more than adequate in terms of a tutorial. This GPU installation video is basically just a part from that video, with a few more bits of info and a better recording setup.
This is really drawn out, and probably pretty incoherent, but this is my opinion.

I don't necessarily dislike the video, I just believe that you've set your channel up in a way that makes this video not a suitable fit for it anymore.
