Dual GTX 570's or a single GTX 680?

I want to build a new gaming computer, but I don't know if I should go with dual gfx cards. I've never used dual gfx cards before, so I don't know how much better they are, or even how they work. If I get the dual gfx cards it will be ~100 dollars more, and I don't know if that's worth it or not.

Or maybe someone has a better suggestion of what card(s) i should get?

P.S. I will be playing games like Battlefield 3 and Skyrim.

2 GTX 570s outperform a single GTX 670 and sometimes a GTX 680.
But the GTX 680 is the best option to go with because 2 GTX 570s consume much power, will run hotter than a single card, SLI doesn't always scale well, the 1.2GB VRAM sometimes is a major stutter and bottleneck for certain games.

2 GTX 570s = GTX 590 (that in case you get the proper scaling of GTX 570s in SLI)
GTX 680 is 3-5% slower than GTX 590, If you OC it there will be no difference.

Get a GTX 670 and with the money you saved buy dual 23" monitors.

If I was building brand new I would get a 670 or 680.

If I already had one with a 570, already had a PSU and mobo to support it, I would add another 570.

If I already had one with a 570, but needed to buy another PSU or mobo to SLI it, I would just buy the 670 or 680.

Since you're building new, pick up the 670/680 but make sure you buy a mobo and PSU that will allow you to toss in another 670/680 so when BF4 comes out, you'll be ready.

You want to weigh cost, but also card sizes, heat, noise and think, 3 years down the road.

I was in the exact same boat as you, but was deciding between a pair of 580s or a single 680. I went with the gtx 680 and could be happier. I plan to get another 680 in the future for SLI. I got lucky and snagged a 680 for $500 which helped with the decision too.

I wouldn't pay the rediculous prices the 680s are at with some retailers if you can wait. I'd keep check retailers that are listing them "out of stock" and hope you get lucky like me. However if you can't wait then I'd try for the 670 which is almost as good as the 680.
 
Twin 570s will outperform the single 670 in the majority of games. The 6xx series (@ 55%) also doesn't scale as well as the 5xx series (@75%) did....at least w/ current drivers. Multiple all the fps in the graphs here for the 570 by 1.75 and you see:

the following advantages for the twin 570's:

BF3 - 27%
Dirt 3 - 36%
Skyrim - 88%
Metro 2033 - 38%
Dues Ex HR - 47%
Batman AC - 570 loses (670 is 13% faster than twin 570's

The scaling is misleading. The problem isn't that they don't scale as well, it's just that at 1080p, the CPU will bottleneck before the SLI 670/680's will hit their full performance.
