When MSI first launched their Z97 Gaming Series motherboards they were made up of the Z97 Gaming 3, Z97 Gaming 5, and Z97 Gaming 7. MSI has now introduced a new high-end addition, the Z97 Gaming 9 AC. This board is targeted directly at high-end gaming PC builds.
Intel is expected to launch the next generation 9-Series chipset on May 11th which will include the latest Haswell refresh processors and various Z97 and H97 motherboards from different companies. It looks like MSI’s entire Z97 Gaming Motherboard line has been leaked.
