hey guys i know i am really slow on new stuff and all and you guys may already have talked about this
but i just saw this EVGA Classified SR-2 (Super Record 2) board and for real dude it's awesome! but i saw some things on the board i have no idea about and if anyone can maybe explain to me a real quick that'll be awesome!

you see how on the motherboard there is alot power sockets, next to each cpu socket there is 1 2x4 and 1 2x3 but on the side of the left socket there is another 2x3 what are the 2x3s? i have never seen those before......
also what if i want to use it do i have to get an adapter for it? because i only got a 850Antec (the yellow one)
oh yeah two more things...

is this a server board or is this a real overclocking board like the R3E or the Classified?
i saw this thing have USB3.0 but didn't see anything about it's having SATA3.0
well, dose have SATA3.0 or no?
