If you're looking to experience true 3D gaming, look no further than the NVIDIA GeForce 3D Vision. You'll feel like you're really in the game, and the biggest plus - the glasses aren't hideous. I'm willing to bet Kanye West would gladly sport those babies.
There are already a couple games ready to support the GeForce 3D Vision; Left For Dead and WoW: WotLK, just to name a few. The 3D glasses are of the powered variety, not the blue lens/red lens kind that you get at a 3D movie. They charge via USB, so you shouldn't have a problem keeping the battery topped off. To use the set, you'll need a display that supports 3D, such as Samsung's 2233rz.
The GeForce 3D Vision package will put you down $199, but if you're the type that constantly upgrades your rig for gaming, you probably won't mind. The set will be available within a few days.
