Upgrading to Asus P8z77 mobo but which one?

Thnx
I think the choice remainly depends on what you use ( pci/ sata etc) i dont use the soundboard or wifi
I have 1 sata1 hd, 2 sata2 hd and 1sata3 ssd . I dont use raid. In the near future i will be using more ssd for my sample libraries when they become cheaper. And these will replace the sata2 hd’s
