Oh no it didn't! But it did, MSI pretty much took a jab at ASRock and said that it has the very first motherboard with PCI-Express 3.0. Now, ASRock made a similar announcement earlier this week so the title of 'world's first' will be decided through retail availability.
Title-caving aside, MSI's Z68A-GD80 (G3) is quite an enticing LGA1155 board as it features three PCI-Express x16 slots (PCIe x16 3.0 deliver a bandwidth of 32GB/s) for SLI or CrossFireX setups (Virtu technology is also supported for some on-the-fly graphics switching), Military Class II components (Hi-c CAP, Super Ferrite Choke and Solid caps), four DDR3- memory slots, and ten SATA ports (probably four SATA 6.0 Gbps and four 3.0 Gbps).
MSI's PCIe Gen 3-enables solution also boasts the OC Genie II overclocking function, voltage read points, dual Gigabit Ethernet, 7.1 channel audio, DVI and HDMI outputs (apparently), two USB 3.0 ports on the backplate (plus two via a header), and also FireWire and eSATA connectivity.
According to MSI, the Z68A-GD80 (G3) will become available in early Q3 (aka later this month).
