The TUF series (The Ultimate Force) Sabertooth 990FX is what we'll be placing under our microscope today, styled in the very same color as the earlier models with the ceramic design we see a lot of resemblances. But hey no tactical jacket anymore though. This AM3+ motherboard will be powered by a 10-phase Digi+ VRM. Socket AM3+ will support the Bulldozer based Zambezi FX Series Processors which launch later. The Sabertooth 990FX will come with four DDR3 DIMM slots supporting dual-channel memory up-to DDR3-1866 MHz straight from the EFI BIOS. What you'll also notice is that the TUF (The Ultimate Series) has four PCI-Express 2.0 x16 PCIe graphics card slots based on what you use the slots for of course. Interesting fact is that this motherboard series now is SLI compatible.
