Plus,I think you forget the $250 8800GT matched performance of the $650 8800GTX for most intents and purposes in the game. That would be the equivalent of a GTX1060 or RX480 matching a GTX980TI at launch. Emm,yeah that never happened.
You are forgetting a lot of details. The 8800 GTX was built on the G80 chip which was 90nm. The 8800 GT was built on a die shrink of the same chip. It was 65nm and that came with a performance increase as well as been cheaper to produce. And it wasn't released until almost a year after the 8800 GTX. You are also forgetting that the 8800 GTX wasn't $650 when the 8800 GT launched.
So what most accurately describes the chip you are looking for is a die shrinked version of the 980Ti at a $300-$350 price point.
The 8800 GT was an amazing chip. But, don't forget that it is 65nm vs 90nm. And because it was just a die shrink, there was no new process, it was very cheap for Nvidia to produce, hence the price.
As I said already, the 1060 would be the equivalent of a 8600 GTS back then.
But, it's looking back at the past through rose coloured glasses and seeing what you want to see.
