Re: Is 3D Vision worth the performance hit?
Worst case scenario is that it cuts your FPS in half. In most real gaming situations with 3D Vision, the performance hit isn't as bad. Most likely it's because even though its rendering a different image for each eye, it is still using the same assets in each frame.
As for whether it is worth it, that all depends on how your stance is with 3D viewing in general. If 3D gives you headaches, then no it probably isn't. But for me it has added an extra level of immersion and wow-factor into games.
A single GTX 480 will probably be enough to handle most games in 3D on a single monitor at 1080p maxed out. A select few like Metro 2033 will probably require you to turn down settings to get acceptable framerates in 3D on a single GTX 480.
