Which would you rather have? I think I would prefer the nvidia 3d. I don't think the eyefinity is anything special. Just more screen you can't really stare at without taking your attention off of others especially in FPS games online. 3D aspect just sounds like massive fun though.
Considering they're totally different technologies you can't exactly compare them, can you.
Nvidia 3D doesn't mean *** to me because I use multiple screens for my work - Eyefinity gaming is just an extra feature, not the entire point of the technology.
Eyefinity doesn't mean *** to my brother because he loves all the latest gaming toys.
I'd vote for 3D, since I wanna watch Avatar in 3D when the BD version is released .. I have a wall-mounted Pioneer 50" plasma about 4 ft. from my desk, as a gaming monitor, so I don't really need multiple screens for that 'total immersion' effect.
I don't think I could get used to multiple screens until they make them without a bezel, for a seamless transition from one to the next.
Of course, ideally we'll get Eyefinity + 3D with bezel-less monitors eventually..
I'd prefer eyefinity just because of the versatility. Honestly, I don't see the interest in 3d, i went and saw alice in wonderland in 3d and that's not at all how we see things, so its not really appealing to me.
now, also being a programmer and a person that uses media creation programs a lot, i'd prefer eyefinity because of the extra space it gives you to work with. Down side is that its expensive
With the new release of the 10.3 (scroll to the bottom) driver, ATI's cards just got support for stereoscopic 3D imaging. So you would probably have to have a super beefy card for this but you could potentially have a three monitor eyefinity with 3D. Pure awesome!
