The 680i architecture is really starting to age (Thanksgiving of 2006), also the ability for that board to over clock to the extremes tends to be on the weakside or unstable (1066mhz native and support for 1333mhz). Albiet the price of the boards are falling and both 16X channels work electrically at 16X, but your gonna reach a point when XFX will stop support on the board. This translate into few upgrade options in the future especially when newer revisions for 45nm processors come around. I would suggest to shop around for a good 750i board if you dont care about triple sli. This will move you to a board that is native 1333mhz and 1600mhz support and newer processor support with the drivers to accommpany them.
