Firstly no, i was not one of those people. Secondly are you seriously suggesting that buying something that most people, and even a lot of games, don't use 'ultrawide' and a bigger library of games are the only selling points for why someone would spend money to stick a graphics card in their PC rather than just go out and buy a console.
And that's even before we factor in that i was talking about people who already own a PC, something that's becoming an increasing rarity these days. If someone wanted to get into gaming on the PC for the first time you're probably looking having to double the cost of a console for a bare minimum setup, that's not a good place to be in for something I've been an advocate for my entire life. If someone came to me now and said they were considering buying a PC for gaming and general home computer use I'd find it hard not to suggest they simply don't bother as they can get a similar, more hassle free, experience with a console and a decent notebook or tablet, and it may even workout cheaper.
