the footsteps of some usual suspects, MSI has announced its first duo of AM3 motherboards. First is 790FX-GD70 followed by IGP 790GX-G65. Both of them support, yet to be released AM3 as well as the AM2+ processors and with AM3 comes DDR3 support. Boards also have MSI's Active Phase Switching (APS) power-saving technology.
The 790FX-GD70 is based on AMD's 790FX chipset paired up with an SB750 southbridge, has four PCI-Express x16 slots and it can work in two times 16 or four times 8 mode. Other noted specifications include support for dual-channel DDR3 1333 with up to 16GB in four slots, MSI's DrMOS, dual Gigabit LAN, integrated 7.1-channel audio, eight SATAII and one eSATA port, twelve USB 2.0 and a singe FireWire port.
The 790GX-G65 is based on AMD's 790GX chipset and the same SB750 southbridge, has two PCI-E x16 slots with support for ATI CrossfireX and Hybrid CrossfireX technology. It comes with four DDR3 1333 memory slots with support for up to 16GB of memory. Other specs include Gigabit LAN, five SATA II ports and one eSATA port, and the same integrated 7.1-channel audio.
Both motherboards are equipped with 5-phase PWM with MSI's APS system, a BIOS-level power-saving technology which is OS independent. The MSI APS is also switching phases for chipset and memory as well.
According to our info, both motherboards should be available on 9th of February, but the price remains a mystery.
