The GA-990FX-Gaming AM3+ ATX Motherboard (rev. 1.0) from Gigabyte is designed to fit in cases that support the ATX form factor. It supports AMD AM3+ FX, AM3 Phenom II, and AMD Athlon II processors in the AM3+ socket, as well as the AMD 990FX and SB950 chipsets. This motherboard supports Windows 8.1, 8, and 7, as well as Linux and Win9X/ME/2000/XP with available drivers.

The ATX form factor of the GA-990FX-Gaming has 4 x DIMM slots that can support up to 32GB of RAM, as well as dual memory architecture and Extreme Memory Profile (XMP) memory modules. The supported memory speeds are 2000 (OC), 1866, 1600, 1333, and 1066 MHz. This motherboard has a total of 6 x SATA III 6 Gb/s ports, 1 x M.2 connector, 2 x PCIe 2.0 x16 slots (running at x16), 1 x PCIe x16 slot (running at x4), 3 x PCIe x1 slots, 1 x USB 3.1 Type-C port, 1 x USB 3.1 Type-A port, 4 x USB 3.0/2.0 ports (2 ports on the back panel, 2 available through the internal USB header), 12 x USB 2.0/1.1 ports (6 ports on the back panel, 6 ports available through the internal USB headers), and 1 x PS/2 port. Using the Realtek ALC1150 codec, it can support 2, 4, 5.1, and 7.1-channel HD audio.

The GA-990FX-Gaming does not support integrated graphics and also does not have any video-out ports. Users will be required to purchase their own dedicated graphics card for use in any system utilizing this motherboard. However, there is support for 2-Way AMD CrossFire and 2-Way NVIDIA SLI technology.

The GA-990FX-Gaming has also been designed with an upgradable OP-AMP, a digital-to-analog audio converter, Gigabit Ethernet, DualBIOS (UEFI), and more. It is protected by a limited 3-year warranty.
