As Tenebrousedge already stated, you're talking about websites related to gaming that are recommending NVIDIA.
I personally have used Linux exclusively (both on desktop and laptop computers) since 2003. I have also used AMD GPU & CPUs exclusively since 2008. The most graphics intensive thing I've ever run is Youtube in Firefox. My current video card in my primary workstation is from 2011.
My wife and young children have no problem navigating my linux based systems. We as a family use it for regular every day things such as browsing the web, writing documents, watching netflix, downloaded movies and music. I will admit we don't play video games, and do not own any gaming consoles. I encourage my children to go outside and play (we play a lot of soccer in the field next to our home), or do something more constructive like building things with Lego or Meccano.
The only people who care about the latest and greatest graphics and drivers are gamers. Period. Frankly, Linux is not for them. The Linux community accepts and understands that. Most of us would rather the masses stick to what they know.
