It looks as
if three-way SLI is closer than anyone would've expected and the upcoming GeForce 780i and 780a chipsets will support this natively.
The good news here is that those that own a board based on the 680i chipset can also enjoy three-way SLI and it might be as soon as this year.
The first cards to have support for three-way SLI will be the 8800 Ultra and GTX with more cards to follow. We can't see too many people investing in this though, considering the cost of three high-end graphics cards.
A new SLI bridge connector will also be needed and it's anyones guess where you'll be able to get one of those from for your 680i board.
