No gradeGigabyte 990FXA-UD3 Motherboard
If you are looking for a mainstream socket AM3+ motherboard based on the high-end chipset 990FX, the Gigabyte 990FXA-UD3 may be an excellent option. It comes with six SATA-600 ports, four USB 3.0 ports, and four PCI Express x16 slots supporting both two-way SLI and CrossFireX. One other highlight of this motherboard is the excellent audio codec (108 dB SNR for the outputs and 106 dB SNR for the inputs). If you want to build a gaming or multimedia PC based on the AMD FX processor, and don’t need fancy features like lots of extra SATA-600 or USB 3.0 ports, the Gigabyte 990FXA-UD3 is a good choice, since you can save some bucks to invest on a more powerful video card.
