680 SLI now or wait for 700 series?

 With Titan being evidence of what's possible with the right combinations.

Do you guys think waiting for the 700 series with a 590 to be best, or Buy 2 680s now for a hefty short term upgrade?

With that said, do you guys think SLI 680s will be good enough to be solid 3 years from now?

you have, currently, a 590? in that case i would say stick it out until 700 series

the 590 is still a powerful card, and should max out most games. (what monitor setup are you running?)

680s 3yr furture proofing? of course!, a single 680 can max most games anyways

 

 3x 23" 120hz mons in surround.

My main concern is the 680 sli compared to its 700series eqv.
 Revolution or Evolution, if the 680 sli is only like 10-20ish fps lower or 20-30% lower in performance then we might as well stick with it.

I don't know enough about Nvidia to know what they might do with the 700s vs the 600.

So you want to run Nvidia surround? on 3 monitors? That's going to need some serious horsepower and budget. At the end of it all what do you want to pay? Because right now i'm thinking 3 680s, as 3D, triple mons are extremely demanding.
