GeForce 300 series
The GeForce 300 series is a series of Tesla-based graphics processing units developed by Nvidia, first released in November 2009. Its cards are rebrands of the GeForce 200 series cards, available only for OEMs. All GPUs of the series support Direct3D 10.1, except the GT 330 (Direct3D 10.0).

History 
On November 27, 2009, Nvidia released its first GeForce 300 series video card, the GeForce 310. However, this card is a re-brand of one of Nvidia's older models (the GeForce 210) and not based on the newer Fermi architecture.

On February 2, 2010, Nvidia announced the release of the GeForce GT 320, GT 330 and GT 340, available to OEMs only. The Geforce GT 340 is simply a rebadged GT 240, sharing exactly the same specifications, while the GT 320 and 330 were newer cards (albeit still based on the previous generation GT200b and G92b architecture).
