Great video tom! nice to see you have the whole family of crosshairs together (I would like to see the crossblade in there too but I guess it would be a bit off-topic)
Two sidenotes: Audio, I guess asus would have thought "if they are paying that amount of money they can buy their own fancy audio cards"
e-sata: really really good stuff if you do a lot of IT-support stuff, e-sate is just the normal sata interface, with usb 2.0 you didn't get the full sata speed and the usb protocol had some overhead which slows down drives and has some problems with large file transfers, ALSO, you get full acess to the drive as you would in a normal sata... External boot ssds/hdds were a thing for some people
