You can still use Z87 on Devil's Canyon CPU. Just need to update BIOS for latest CPU microcode.
There's a newer version of the MSI Z87 GD65, the Z97 GD65:

The differences are minimal. The Gaming 7 has M.2 and the GD65 has mSATA.
Plus the Gaming 7 has more overclocking room for the RAM, witch can be overclocked to 3300Mghz. 300mgz more than the GD65.
