What would give me greater gaming performance in terms of FPS, a single GTX 680 or GTX 570 SLI configuration? I already own a GTX 570, so it would be cheaper to buy another GTX 570, but I’m open to paying out more for the GTX 680 assuming its better overall.

Thanks,
Sam

2.0 x16/8 in SLI isn't that big of a problem. In 1 card mode for 680, you're perfectly fine. In SLI, it's like 96%.

Since you already have a 570, I'd just SLI it. It'd be much cheaper and since you're running 850W, you won't have to change anything.

At the same time, I think a 2500 will bottleneck a 680 SLI anyways so the next upgrade would be a new system maybe around Haswell's release. So I'd just get SLI 570 and then do a complete upgrade later on.

^^I do believe that a 680 in SLI can run on the i5 CPU with out any problem unless you know something I don't know. The i5 is a very good gaming CPU weather it be a 2500 or a 2500k it will be able to handle the 680 or even two 680's.

But I have been wrong in the past before but I think I have it right this time. You might be thinking the i3 would have a bottle neck issue for sure. But most of your post is right on the money.

@OP
Here are both cards the first one is the 570 in SLI and the second one is the 680 single card I tried to get both on the same page but it wouldn't do it.

Agree with sunnk and yialanliu if the gtx 680 sli gets bottlenecked by an overclocked I5 2500K then nothing on the planet will handle 2 gtx 680's.
