It looks like Santa has some elves undercover at NVIDIA, because they've got some goodies to give away to holiday gamers. Here's the scoop:
Starting December 12th (today!) and ending on the 23rd, each day NVIDIA will be giving away prizes on Facebook. Prizes are sorted into tiers based on how many new fans they've gained, so the more new fans the better. On top of that, anyone who refers a friend to become a GeForce fan will receive extra entries to win for each friend that accepts that invitation.
These are the tiers:
Tier 2 (3000 fan increase): GTX 560
Tier 3 (4000 fan increase): GTX 560 SLI
Tier 4 (4500 fan increase): 3DV 2 Monitor and Glasses
Tier 5 (5500 fan increase): GTX 580 SLI and an x79 motherboard
To enter, navigate yourself to the NVIDIA GeForce Facebook fan page, then look on the left side for "12 Days of Gear Up Giving". Click there, follow the directions to enter, and invite your friends to better your chances.
Remember the last day for prizes is the 23rd of December, so the sooner you get in, the better.
Legal note: This is only open to legal residents of the United States of America (excluding Puerto Rico and its other territories and possessions), Canada (excluding the province of Quebec), the United Kingdom, Germany, Norway, Australia, and Brazil. All entries, whether online or by mail, must be received no later than between 9:00 AM on December 12, 2011, Pacific Standard Time and 5:00 PM on December 23, 2011, Pacific Standard Time.
