Just buy it is famous because no testing went into the statement. It was a blind recommendation on a site that used to be famous for data driven recommendations. That is why it is a famous line and very different than pointing out a psychological reason people purchase these cards after doing a review.
I can tell you, I have spoken to a dozen local companies in the valley that will not buy their DL/ AI engineers less than Titan RTX's for workstations. There is such a big shortage for top talent, that 0-2 years out of school there are folks, that are great at computer vision as an example, making $400K+ in addition to equity-based comp. If those folks do not like the job, they just leave and go to another company that will pay them the same or more.
In that context, $3000 or so per GPU to minimize frustrations and keep one person from jumping to a competitor or another company is huge. I have heard it now on numerous occasions.
To me, the funnier part is that most of those same companies have large clusters. It is still effectively an HR move to keep people and attract others. These guys go to bars and tell everyone their company buys them Titan RTX/ Tesla V100/ DGX Stations/ Quadro RTX and those who have RTX 2080's become interested in joining a place with better hardware. If you have a 48GB card, and can run models in-memory that others at the bar cannot, people think your company is helping the data science. Keeping one person retained/ or generating a new hire lead pays for everyone's GPUs.
