AMD's 790X chipset was featured as one of the first in 7-series chipset family. Based on the RX780 chip, this chipset is essentially identical to the AMD 770, except for that it supports the ATI CrossFireX technology. With the introduction of the 790GX, the 790X was less opted for. The chipset made its comeback with motherboards from Gigabyte and MSI that support AM3 processors and DDR3 memory. ASUS is ready with its competitive motherboard based on the AMD 790X + SB750 chipset. The ASUS M4A79XTD-EVO offers some of ASUS' latest innovations.

To begin with, this socket AM3 motherboard supports DDR3 memory. The CPU is powered by an 8+2 phase power circuit, that is controlled by the ASUS EPU active phase switching controller. The brown PCB uses a 2 oz copper to reduce EMI and enhance electrical stability, a technology found in Gigabyte's UltraDurable 3 motherboards. The 790X northbridge connects to two PCI-Express 2.0 x16 slots (electrical dual x8, when both are populated). Two each of PCI-E x1 and PCI make for the rest of the expansion. The SB750 southbridge supports AMD Overdrive and Advanced Clock Calibration (ACC). Apart from the six SATA II ports it provides, an additional controller gives out one internal port, and an eSATA port. Overclocking is aided by the TurboV feature. VIA VT1708S onboard 8 channel audio, Realtek Gigabit Ethernet make for the rest of the package. ASUS will have this board up in the next few weeks.
