People like to watch videos of $2000-5000 rigs as fantasy porn, moreso than informative or practical consumer recommendations. It's vicarious living, watching someone else enjoy luxuries and feeling like we are experiencing it ourself. To quote Luke, "our most watched video is the review of the GTX 1080 even though most people can't afford a GTX 1080".
I'm willing to bet that at least the majority of people who watch those videos have a computer that's crap or dated, possibly running on integrated graphics. Deprived people think about corvettes and lamborghinis - not toyotas. Cake - not bread. Straight hood mentality.
ripjaws has more red in it but the dominators have more a e s t h e t i c instead of red everywhere, and you get to brag you have stupidly expensive ram
the ripjaws red look closer to the MSI red than the domintor red
