To experience my games in incredible 3D I've always choosen Nvidia graphics cards. The reason for this is simple... Nvidia support 3D gaming with their own 3D stereo drivers.

Here's what Nvidia have to say about 3D gaming.
Imagine immersing yourself in the world of 3D content like never before. Monsters, bullets, and landscapes jump out of your flat monitor and into your imagination, making you part of the game. With NVIDIA® 3D Stereo, gaming will never be the same.
Thanks to the tight integration of our drivers and NVIDIA's customized stereoscopic 3D support, NVIDIA 3D Stereo is the fastest consumer 3D stereoscopic solution available today, resulting in games that look the best and run the fastest.
In addition, NVIDIA 3D Stereo works on the broadest range of applications, making it the most compatible 3D stereoscopic solution ever available. Previous implementations of stereoscopic 3D support have been proprietary to specific graphics cards, stereoscopic glasses, and special versions of games. Now, NVIDIA 3D Stereo brings stereoscopic 3D support to our whole family of TNT™-, GeForce™-, and Quadro™-based graphics cards running games developed with Direct3D® and OpenGL® APIs without requiring special versions of your favorite games. In other words, 3D Stereo will work with your existing game library!
