Its two PCI-Express 2.0 x16 slots (electrical x8, x8, when both are in use,) provide support for ATI CrossFireX. The SB710 southbridge takes care of six internal SATA 3.0 Gbps ports, an IDE connector for two devices, 8-channel HD audio, and support for Advanced Clock Calibration. Gigabit Ethernet, six USB ports and a serial port, make for the rest of its connectivity. The MSI 790X-G45 will be available in the weeks to come.
