You can still use this board with air or water, its a top of the line board from Gigabyte....mite be worth waiting thou m8 as there are only a handfull of P55 boards out at the sec, i would personally wait till you have read some more reviews on your different options!
Yeh.... im not considering to get the board straight away, im waiting until the end of year where more P55 board will be out (at least by then i hope), but yeh, i'll wait till there are more reviews about it.
