Most graphics cards are sold in pre built systems not DIY purchases. But that has no bearing on enthusiasts on tech forums making excuses for cards like that RTX5070 which are frankly poorly specified for the price. Its like saying the Fiesta is a better than a Bugatti because it sold more. This is what happens when people enter echo chambers and are obsessed about branding than calling out poor products.
Do you not think supply and price has anything to do with it or will it be driven by this difference. Definitely agree, pre-built systems will have an impact.
