Until nVidia launched their 400 series chipset they'd been behind ATI/AMD since the 9000 series. Basically nVidia had no answer to the ATI/AMD 4000 series chipsets and to be frank, if it wasn't for the 8800GTX and the 8800 Ultra even the nVidia 8000 series would have run 2nd place to ATI/AMD's 3000 series. Even discounting that, that's several series of 'also ran' chipsets against the 4000 series chipsets.

The GTX 200 was acknowledged to be the same if not a bit faster than it's 4000 counterpart, so that is untrue. The 4000 series was ATI returning to being competitive with Nvidia after the 3000 series. Certainly the GTX 285 was faster than the 4870 when launched.
I have to call you out as your post was way too biased and generalised. The reality is that Nvidia and ATI have been trading blows all the way down the price range for the past few years. The only time ATI have had outright superiority is when Nvidia have not turned up to the party, with late GPU refreshes. 400 series was hideously late.
Nvidia normally put out faster GPU's, by using dumb brute force of more transistors, which means their GPU's are normally too hot and consume vast amounts of power. ATI on the other hand make optimised GPUs that need less transistors and so are cooler etc. GPU's that are great, but just are not as fast as Nvidia's monsters GPU vs GPU.
The side effect is that Nvidia with their approach have been late with their GPU's recently due to manufacturing complexity, so ATI have had months competing against old Nvidia GPU's. And as a second side effect Nvidia have big problems fitting two GPU's on to one card, so ATI get to claim fastest card.
Who has the fastest single card, was always a dumb battle. Who cares about about how many down clocked GPU's you can shoe horned on to a single card, when it is much more useful to know who has the fastest GPU and then buy two of those cards for about the same price instead. Why pay a premium just to have two GPU's on one card.
The GTX 280 was the same or faster than the Radeon 4870
The GTX 480 was the same or faster than the Radeon 5870 (but months too late)
The GTX 580 is than the AMD 6970
