I actually explicitly said not counting cards like the GTX285 and 8800 Ultra because they technically came out after the initial lineup launched. They were usually just super high-end offerings that were made to address performance deficits or because they could. In the case of the GTX580 3GB, it was because super high-end users needed more VRAM, this only really affected people using 3 Display setups, so it was an incredibly niche product.
If we wanted to go crazy there are all sorts of products released that are technically better, the HD5970 is to this day ridiculously powerful, and surprisingly cost efficient. I also omitted the HD4890, because it was launched months after the rest of the 4xxx series.
My listings are still accurate. There are outliers, but for the most part all of those cards were the original high-end GPU of their corresponding series.
