Chip company Nvidia has sent invitations to press for an event called "Made to Game," which will be held March 3 as part of the Game Developers Conference in San Francisco.

During the hour-long presentation, Nvidia's president and chief executive officer Jen-Hsun Huang will make what sounds like a major announcement.

"More than 5 years in the making, what I want to share with you will redefine the future of gaming," reads a line from Huang's invitation to media.

He also referred to the presentation as a "very special event." No further details were made available, but GameSpot will be on-hand during the event to bring you all the news.

In addition to whatever Nvidia has up its sleeve, Valve plans to show off its line of Steam Machines--and maybe the final iteration of the Steam Controller--during GDC. On top of that, GDC will also bring us a first look at Assassin's Creed eye-tracking functionality.

GDC runs March 2-6 at the Moscone Convention Center in San Francisco.
