i think the sabretooth is the best of the p67 boards but its old, and tbh as are the z68 now with z77 so close.
i picked up a z68 d3 b3 for now as they are cheap and then i will be getting a z77 when they are out so i can drop an ivy chip in later and have all the features, not sure i could tell anyone to do anything else atm with my hand on my heart you know.
