I have a GTX 570 EVGA and a GTX 680 EVGA SC+ w/Backplate being shipped as we speak. Can I put a SLI on these cards or do they HAVE to be same (i.e. x2 570's)

IDC if the GTX 680 is bottlenecked by the 570 lol as long as it is = to 570 sli. Let me know guys, THANKS!

They have to be the same unfortunately , you can only SLI a 570 with a 570 etc.
You would be better off to use the 680 and sell the 570, and get another 680 in the future to SLI.

Once you get the 680 you will be happy, the performance on them is excellent, you will want to give your friend his 570 back.LOL

No, you can not sli two different cards.

For SLI configuration you have to make sure of the following list:-

1)Both have same chipset model irrespective of the company.
2)Both should have same clock,memory,shaders,etc.
3)SLI labelled motherboard.
4)Enough power to power both the graphic cards at the same time.
5)Standard psu with SLI label.

That part's not accurate. 2 cards of different speeds will SLI/xfire just fine. The faster cards will clock themselves down to the slowest. However, You do need to make sure both cards have the same amount of memory. A 1gb 6950 and a 2gb 6950 cannot be xfire'd.

Actually a 2GB 6950 and a 1GB 6950 can be crossfired, but the 2GB card will only use half of its memory. Crossfire does tend to be more flexible than SLI when it comes to supporting differing cards, as two cards of the same series will Crossfire, like a 6950 and 6970, with the faster card slowing down to the speed of the slower card.

SLI tends to be more picky, you have to have the same GPU, memory, and shaders. In any case the OP should be quite happy with just the 680, he'd only need more if he wants to try and max out Crysis 2 at 5760x1080 or some other ultra high resolution.
