^ive heard 3d is gimmicky trash, just sayin...
never tried myself but personally id rather have 2d surround which you pretty much need 2 top gpus for anyways
Most people who call it gimmicky trash have never used it and are just paroting what they hear, or caught a 3D movie, that was done the way they usually are (after the fact altering that make it look like cardboard cutouts). When done well, it's amazing.
I've used it, and still use it. If it's an option on an action game, I use it. Crysis 2, Metro 2033, The Witcher 2 and others look spectacular in 3D Vision.
The down side is some people get headaches from it (I don't know the percentage, I think some of it is due to low FPS) and obviously if you have 1 working eye, you won't get the effect.
If you haven't used it, I'd just not mention it. It's a shame when people spread rumor not based on experience.
