Following announcements by most motherboard manufacturers about their AM3 CPU compatibility lists, plans of motherboards based on the new DDR3-supportive platform socket have been coming to surface. After a list of eight motherboards by ASUS under the M4A and M4N series, Gigabyte's first motherboard based on the AM3 socket has been pictured. The GA-MA790FXT-UD5P is the company's first AMD motherboard that uses the Ultra Durable 3 construction, with 2-oz copper layered PCB, high-grade conductive polymer capacitors, and MOSFETs with lower RDS.

As the name suggests, this motherboard is based on the AMD 790FX chipset. It features two full-bandwidth PCI-Express 2.0 x16 slots supporting ATI CrossfireX, four DDR3 DIMM slots supporting DDR3-1600+ MHz memory. The motherboard supports AM3 socket processors with TDP of up to 140W. A total of 10 SATA II ports are provided, six of which are routed to the SB750 southbridge, four to an additional SATA II controller. Other features are common with Gigabyte motherboards in its class, with high-quality 7.1 ch audio, two gigabit Ethernet connections, twelve USB 2.0 ports (8 external), and FireWire. Gigabyte is planning two more AM3 socket models: GA-MA770T-UD3P and GA-MA790X-UD4P based on the AMD 770 and 790X chipsets respectively.
