Will the maximus iv extreme be a good p67 MOBO

i want to know if the asus maximus iv extreme will be a good MOBO for a 4-4.5GHz OC- edit: i guessed  

will it fit 3 radeon 6970s... and i have heard that you can not put normal RAM in it because of the cpu fan- edit: confirmed

what type of RAM should i get i'm leaning towards the OCZ Platinum 8GB (2 x 4GB) 2000 kit



PS. when does this board release, the ninth?

thanks.
