I wouldn't get any asus 680i boards.
Currently the best 680i solution is the evga A1 board.
All the custom 680i solutions (asus, abit, gigabyte, dfi, msi) offer a few extras, and cost more. Furthermore, other then the abit and DFI they OC worse then the reference board.
ASUS get's crap because out of all the 680i boards the striker has by far the most problems. I used to stick with asus and abit (till abit had a bad run), but asus seems to be having problems lately and the striker is the most glaring example.
Their bios updates haven't really fixed any of the most glaring issues.
Stick with the evga. I upgradged my striker for the evga and it was a great decision.
The asus 680i debacle has been so great I'll be wary purchasing anything from them again.
