I have Palit Jetstream GTX 680 4GB in SLI configuration
How exactly would that infect my choice, if I may ask?
AMD HD3D in an active 3D setup, will either require an HDMI 1.4a connection which limits you to 720p at 60hz per eye (for gaming) or 24hz at 1080p (for movies, gaming would suck). Displayport is needed for optimal support.
With Nvidia, you will want a Dual link DVI setup, and for the best visuals, so things aren't very dark, you'll want to go for 3D Vision 2. The ASUS VG278H would be a good choice.
