not sure i agree with the choice to use higher "Founders Edition MSRP" on the older Pascal cards, yet use the lower Nvidia-claimed "Partner MSRP" for RTX Turing cards.
Yeah, it's not even all that consistent within a generation. The MSRP for the GTX 1060 was $249, but the Founder's Edition pricing of $299 is listed here. However, the price listed for the GTX 1080 is $100 less than its Founders Edition pricing at launch. Meanwhile, the RX 580 is listed at $229, which might give the false impression that a 1060 at a much higher price is a better deal. I think it would be preferable if the list stuck to the MSRP for partner cards across the board, since those are the cards people will most likely be seeing.
However, I'm not sure how useful the list is in general. It ignores when each of these cards launched, how pricing compared to the rest of the market at the time of launch, and whether the cards were ever even widely available at these prices. Or the differences in things like coolers or warranties on individual cards. Those things seem like they would be difficult to convey in an article though. Perhaps it's best just to stick with performance recommendations at a given price level, based on current prices.
On the topic of how graphics card prices have compared over time though, PCPartPicker also provides some good charts depicting this. They have these general trend charts that show the average price and overall price range across all cards of a given model, which only cover the last 18 months, but that at least extends to just before last year's cryptocurrency mining shortages, and definitely shows the impact of the more extreme shortages earlier this year...

They also have similar price charts on the pages for each individual card, showing the price history from all sellers tracked by their service in the selected region. You can filter cards using the left sidebar, then just select a card and scroll down below its list of current prices for the chart. These charts default to 120 days, but you can set them to show prices for up to 2 years. This is good for showing how the lowest sale prices of a given product compares over time...

In my opinion, a card selling at or above MSRP after around 2 years is not a particularly good deal, since the average demands of newly-released games have only increased since then. Or at the very least, such "sales" are probably not something worth jumping on unless one really needs a new card right away.
