Which MSI motherboard is good for 5 gpu mining?

Hi,

I have an MSI Z77A-GD80 which has problem with 5x Sapphire Dual-x R9 280X cards. Two of 1x pci-e slots don't work even with just one VGA on the mobo. Furthermore, It just boots with 3 VGA cards, not with 4+. So I returned it to the warranty and they want to change it for me. Which MSI motherboards do work with 5 VGA cards?

Thanks!
