First up is the Z77A-G43 Gaming and the Z77A-G45 Gaming, both motherboards look quite a like, the G43 variant (left) has Military Class III components, four DDR3 memory slots, two PCI Express x16, two PCI Express X1 slots, four regular PCI slots, support for CrossFire, Soundblaster Cinema 7.1, and OC Genie II One Touch overclocked. The G45 model (right) has the same basic specifications, but also has two more PCI Express x1 slots, so only one PCI port remains. Other than that, the G45 variant also adds NVIDIA SLI support.

The Z77A-GD65 Gaming on the other hand is the new flagship model in the gaming series. It has four DDR3 slots with maximum speed of 3000MHz, KillerNIC network chip, Sound Blaster Cinema 7.1 audio, OC Genie II One Touch Overclocking, and three PCIe x16 slots with triple-SLI and CrossFire support.
