The ASUS Sabertooth 990FX motherboard has the following technical specifications as advertised:

CPU - AMD AM3+ FX™/Phenom™ II/Athlon™ II/Sempron™ 100 Series Processors including AM3+ 32 nm CPU, up to 8 cores, up to 140 W

Memory - 4 x DIMM, Max. 32GB, DDR3 1866/1600/1333/1066 Hz ECC, Non-ECC, Un-buffered Dual Channel Memory Architecture

Multi-GPU - Supports NVIDIA® Quad-GPU SLI™ Technology and AMD Quad-GPU CrossFireX™ Technology

Expansion - 3 x PCIe 2.0 x16 (dual x16 or x16, x8, x8)
1 x PCIe 2.0 x16 (x4 mode, black)
1 x PCIe 2.0 x1

USB - ASMedia® USB 3.0 controller : 4 x USB 3.0 port(s)
AMD SB950 controller : 14 x USB 2.0 port(s)

You'll note that despite the new 990FX/SB950 nomenclature, there's really nothing new here that the 890FX/SB850 didn't already offer. USB 3.0 is still not supported natively, and with only six SATA ports available manufacturers are still relying on extra controllers to offer additional ports or eSATA capability. Although the DDR3-1866 memory speed is now officially supported on AM3+ processors, this is a function of the integrated controller, and some overclockers have already gotten up to 1000MHz or more out of the existing AM3 chips. My personal best so far has been 912MHz or DDR3-1824 with an OCZ Platinum XTE kit.

Let's get the board unwrapped and take a look at some of the features.
