PC partpicker said it would take 576w whilst crossfire so I'm not 100% sure about what to pick

another concern besides the psu - the motherboard you've selected is not one i'd consider appropriate for xfire; the secondary pci-e x16 slot only runs @ pci-e 2.0 x4 speed

So what mobo should i choose

i'd choose one that supports xfire with 8 lanes going to each slot. if you're at a loss for an an exact make/model then check out the reviews section. http://www.tomshardware.com/reviews/z77-express-ivy-bri... that's the round-up that the motherboard i linked was included in & have a hunt around the reviews & round-ups for answers to any other issues you have too :)  good luck with your build.
