The authors biases are plainly visible in this article. Reporters should try to be non biased when it comes to reporting facts about hardware. Its biased statements such as this that reporters shouldn't be using, "proving that RTX technology is either too expensive or the gains aren't worth the upgrade just yet."
Obviously the author never considered the facts. First, the RTX 2000 series cards were released after many users upgraded to GTX 1000 series cards because of the significant leap in performance that they offered. Most PC users and gamers don't upgrade every single generation, so there wasn't much reason for many people to upgrade to RTX 2000 series cards. In fact, other sources say that most PC users upgrade their graphics card or entire PC every 4 to 6+ years. Second, when the RTX 3000 series cards were launched, there were component shortages, a pandemic, a cryptocurrency mining boom, and tons of scalpers charging double MSRP or more for graphics cards. That hurt adoption rates. Third, when the shortage finally ended, most of the world was hit with record inflation and rising food and fuel prices. When that happened, buying a new graphics card wasn't a top priority.
Maybe this site needs to find some unbiased reporters that look at the facts on a global scale.
