I suspect I would have said the same thing back then. There are people out there willing fork out that much cash, such as 1080 or 1080 TI in SLI or Vega 64 in CF.
Actually, your exact words were
"what a monster", you seemed to have no issue with the $1,500 price back then. In fact, you can go through that entire thread, there is no outrage about the price, despite it being even higher than the 2080Ti over 4 years ago.
Don't get me wrong, $1,200 is still a crazy price to pay for a graphics card, and way beyond what I'd be willing to spend. However, everyone is freaking out about the price, when in reality it is pretty well in line with the historical pricing of a completely unrivaled king of the hill graphics card. If anything, it's priced a little lower than they have been in the past...
When were those cards priced this much?
I already answered that. The dates I mentioned were the released dates of the cards, and they were priced that much at release.
AMD R9 295X2 and Radeon Pro Duo. The Radeon Pro Duo you can maybe give them a pass on the high price, because they tried to market it as a "Prosumer" product like the Titans, which usually have a higher price tag, but the R9 295X2 was a straight up desktop card priced at $1500(AFAIK still the highest priced desktop card to date).
Both were price at $1,500 at release.
