MSI is approaching the socket AM3+ performance platform with two motherboards based on the AMD 990FX chipset, at the very top is the 990FXA-GD80 detailed earlier. Next to it, is the 990FXA-GD65, which is designed to occupy a sub-$200 price point. The GD65 depends entirely on the chipset for its features, with very little 3rd-party features. It uses a full-fledged 10-phase VRM to power the CPU. To add electrical stability, a 6-pin PCI-E power connector is in place, if discrete graphics cards that rely on slot power, are used. The 990FX northbridge gives out two PCI-Express 2.0 x16 ports, which are wired to two PCI-Express 2.0 x16 slots that run at full-bandwidth all the time. Other expansion slots include four PCI-E x1 and a legacy PCI.

All six SATA 6 Gb/s ports from the SB950 southbridge are assigned as internal ports, while there are no eSATA ports on the rear panel, MSI might bundle an eSATA bracket that extends two of the six internal ports as eSATA. This way, MSI saved the cost of using an additional third-party SATA controller. Other connectivity includes 8-channel HD audio driven by Realtek ALC892 CODEC that supports optical and coaxial SPDIF output; and two USB 3.0 ports on the rear panel driven by an NEC/Renesas-made controller. There's little more to this board than that, for overclockers. There is a rear-panel CMOS reset button, and "Military-grade" components. Instead of using UEFI firmware with its GUI-driven setup program ClickBIOS, MSI used conventional BIOS with a hack that allows it to boot from volumes greater than 2.2 TB in size. MSI also includes BIOS Code Unlocked Technology, which lets users unlock disabled cores on certain CPUs.

Gigabyte's top-tier socket AM3+ motherboard lineup is shaping up in a big way, with a bleeding-edge GA-990FXA-UD7 at the top of the pile. Gigabyte has yet another motherboard to cater to fans of the AM3+ platform, the GA-990FXA-UD5. The UD5 features a more conventional-looking component layout, with the northbridge located where it usually is. You still get the 10-phase VRM from the UD7, the black Ultra Durable 3 PCB, but this board is designed for multi-GPU setups with up to 3 graphics cards: supporting 3-way SLI and CrossFireX.

Expansion slots include five PCI-Express 2.0 x16, of which three (slots 1,3,5) are PCI-Express 2.0 wired to the AMD 990FX northbridge, with electrical configurations of x16/x16/NC or x16/x8/x8. Slots 2 and 4 are electrical x4, wired to the SB950 southbridge. Other slots include a PCI-E x1, and a legacy PCI. Storage connectivity is similar to that of the UD7, with eight SATA 6 Gb/s internal ports, a power-eSATA, and a normal eSATA.

Here are some of the first proper pictures of ASUS ROG Crosshair V Formula motherboard, a set of press-shots leaked to the Czech press, which has since been retracted. The ROG Crosshair V Formula comes in two packages, with and without ASUS Thunderbolt card (an addon card by ASUS that provides Bigfoot Killer NIC and Sound Blaster X-Fi hardware-accelerated audio). The Crosshair V made its first appearance with a box-shot disclosure by NVIDIA announcing SLI on AMD chipset motherboards; later a table listing out specifications of some of ASUS' fist socket AM3+ motherboard was published.

The Crosshair V Formula is a socket AM3+ motherboard based on AMD 990FX + SB950 chipset, supporting AMD's upcoming FX-series processors based on the Bulldozer architecture. It combines the best features ASUS has to offer, targeting both gamers and overclockers. The AM3+ socket is powered by a strong 10-phase Digi+ Extreme Engine VRM, it supports dual-channel DDR3 memory with speeds of over DDR3-2133 MHz. Expansion slots include four PCI-Express 2.0 x16, which configure as x16/x16/NC or x16/x8/x8, with the fourth slot being electrical x4, wired to the southbridge. NVIDIA 3-way SLI and AMD CrossFireX are supported.

Earlier referred to as "Big Bang Conqueror", MSI's next top-end AMD platform motherboard has emerged under its final name, 990FXA-GD80. The socket AM3+ motherboard that supports AMD's upcoming FX series processors, is based on the AMD 990FX + SB950 chipset. The CPU is powered by a 10-phase VRM that makes use of tantalum-core capacitors, and SFC chokes (that don't whine), driver-MOSFETs (DrMOS). Expansion slots include four PCI-Express 2.0 x16, supporting NVIDIA SLI and AMD CrossFireX; two PCI-E x1, and a PCI.

Storage is mostly care of the southbridge, all its six SATA 6 Gb/s ports are assigned as internal ports; a third-party SATA 3 Gb/s controller handles rear-panel eSATA. There are two USB 3.0 controllers, driving two ports on the rear panel, and two via an angled internal header. Other connectivity includes 8+2 channel HD audio with THX TruStudio Pro support, gigabit Ethernet, and FireWire. A number of MSI-exclusives are bundled, including MSI-designed graphical UEFI setup program (click BIOS), and OC Genie II that is overclocking with side-wheels. Expect the MSI 990FXA-GD80 to be out in mid-June, at a US $175~$250 price range.

With the socket AM3+ platform, ASUS wants to rally around its top motherboard brands, including Republic of Gamers (ROG), with the ASUS Crosshair V Formula, and the The Ultimate Force (TUF) Sabertooth 990FX, for AMD's next top of the line 990FX chipset that is designed to run up to four discrete graphics cards. The 990FX Sabertooth keeps up with the color scheme of the other TUF-series members. It boasts of highly durable components. The AM3+ socket is powered by a 10-phase Digi+ VRM. It is wired to four DDR3 DIMM slots supporting dual-channel DDR3-1866 MHz memory, and connects to the 990FX chipset over a HyperTransport 3.1 link.

Expansion slots include four PCI-Express 2.0 x16 (configurable as x16/x4/x8/x8, x16/x4/x16/NC, depending on how they're populated); The electrical x4 slot is wired to the SB950 southbridge, and is placed there to hold PCI-Express SSDs. One each of PCI-E x1 and PCI make for the rest of the expansion. Storage connectivity includes six internal SATA 6 Gb/s ports supporting RAID, two internal SATA 3 Gb/s from a third-party controller, one power-eSATA/USB combo, and one normal eSATA on the rear panel.

Here is the first picture of the M5A99X EVO, an upcoming socket AM3+ motherboard by ASUS based on the AMD 990X + SB950 chipset designed AMD's FX-Series "Zambezi" 8-core, 6-core, and 4-core procesors. The AMD 990X is designed for discrete graphics with up to two graphics cards in CrossFireX. It is likely that the final iteration has NVIDIA SLI support out of the box. The AM3+ Black socket is powered by 8-phase Digi+ VRM, cooled by a large heatsink that sits next to the northbridge heatsink. ASUS came up with a new heatsink design theme. While the P8P67 series uses heatsinks with curvy/wavy fins, the M5A series uses sharp edges.

The AMD 990X northbridge gives out 16 PCI-Express 2.1 lanes split between two x16 slots. When both slots are populated, the graphics cards run on x8 bandwidth. The third black x16 slot is wired to the SB950 southbridge, and is likely x4. Other slots include two PCI-Express x1 and a PCI. Storage connectivity includes six SATA 6 Gb/s ports from the SB950 southbridge that support RAID 0, 1, 0+1, 5, 10 modes; a third-party controller drives two additional SATA 6 Gb/s internal ports. We don't know if there's another such controller handling eSATA.
