I was initially leaning towards the Sabertooth because of its 5 year warranty. Then when I wanted to place my order today something made me look at the P8Z68 Deluxe again - that is why I posted it.
Yes, you have good arguments to go for the deluxe, but I will at most only run 2X cards in crossfire in the next few months and not 3X.
Just as I wanted to confirm pricing and stock on the deluxe to compare to the Sabertooth I was told it's out of stock with no ETA. Sucks
Oh well, since I am eventually only gonna run 2X crossfire and since BT is only a "nice" feature (although I have a USB BT dongle), I am not left with much option anymore but to go with the Sabertooth - im sure (hope) its still a great mboard. Also, I noticed that both have the DIGI+ VRM design according to Asus' site, not just the deluxe
