There are people out there foolish enough to pay that kind of money. My dad's not quite the techie he was years ago (when he taught me all I knew at the time) and I had to stop him from buying a PC setup that he showed me. I realised that he had become an absolute brand***** and I had to talk him out of several parts. He specifically told me that "It's NOT for gaming!" which made me ask him why he had an Intel CPU (at the time, the top Intel CPU was getting slaughtered by the R9-3900X) if it wasn't for gaming. He also had an ASUS ROG Crosshair-type motherboard in the list that cost over $1,000CAD. Remember, this system is NOT for gaiming.
I told him that his BoM was awful and asked him why he chose the Intel CPU. He said "Because PC World and PC Magazine both recommended it." which just made me roll my eyes. I brought up Techsopt's review of the R9-3900X and showed him how it slaughtered the CPU that he wanted to get by a country mile.
In the end, I got him to "downgrade" to an ASUS TUF GAMING motherboard (he INSTISTED on only ASUS like a noob) then he asked me why I chose the TUF "GAMING" motherboard. After overcoming the initial shock of this man who had always been my tech mentor as a kid who was now back to being a noob, I pointed out to him that ROG means "Republic of Gamers" and that ALL high-end PC parts like that are geared towards gaming. I initially told him just to get an ASUS Prime (because he's not gaming, overclocking or anything strenuous) but he didn't want the "entry level board" (no X570 motherboard is truly "entry-level" but I didn't want to argue over it) so I suggested the TUF and he finally agreed. I actually wanted him to get a Gigabyte board.
In the end, I doubled his RAM, doubled his NVMe space, increased his CPU performance, etc. while REDUCING the cost of his build by $400CAD (yeah, his list was THAT bad). In a flash of Karma, his TUF motherboard gave him headaches with the sound so he had to RMA that and I had to loan him my ASRock X370 Killer SLI (with updated BIOS for Ryzen 3000). No issues after that have been seen. I only feel bad that I recommended one of those exploding Gigabyte PSUs. He needs to send his in because it is one of the ones on recall. At the same time though, he doesn't do anything that stresses the PSU in the least.
This shows, as much as the RX 6900 XT and RTX 3090, that no matter how bad a deal you make something, if it's pretty enough, some noobish fool will buy it.
