Did Nvidia skip the 800 series for graphics cards?
GeForce 800M series
Nvidia has announced that the company skipped the GeForce 800 series for desktop graphics cards, most likely because the GTX 800M series consists of high-end Kepler and low-end Maxwell based components. Instead, Nvidia had announced that the newly renamed GeForce GTX 980 and GTX 970 will be introduced formally on September 19, 2014.[2]

On April 7, 2010, Nvidia released the GeForce GTX 470 and GTX 480, the first cards based on the new Fermi architecture, codenamed GF100; they were the first Nvidia GPUs to utilize 1 GB or more of GDDR5 memory. The GTX 470 and GTX 480 were heavily criticized due to high power use, high temperatures, and very loud noise that were not balanced by the performance offered, even though the GTX 480 was the fastest DirectX 11 card as of its introduction.
