Asus Sabertooth 990FX Motherboard Review

Rating: 9.0.

Today AMD are launching their new 990FX chipset motherboards and we are looking at the Asus Sabertooth model which is a board loaded with a plethora of features. The Ultimate Force (TUF) Sabertooth 990FX has a 10 phase Digi+ VRM and it is wired to four DDR3 DIMM slots which support dual channel DDR3 1866mhz. This connects to the 990FX chipset across a HyperTransport 3.1 link.

No one will argue that Asus make some of the finest motherboards on the market. Their Republic Of Gamers (ROG) and Asus Crosshair V Formula motherboards have won many awards across the globe. My personal favourite right now is the Asus Rampage III Black Edition X58, which scored a staggering 9.5/10 when it was reviewed on Kitguru in March.

The Asus Sabertooth 990FX also supports both Quad GPU SLI and Quad CPU CrossfireX. Is this one of the best AMD based gaming motherboards on the market? On paper it certainly looks like it.

Aerocool Project 7 C1 Pro Chassis Review

Its a new 'PRO' version of the Project 7 C1 we reviewed some time ago - what exactly is 'PRO' about it ?

  • Jeffrey

    Funky colour scheme…. looks very similar to the ‘army’ MSI boards ive noticed in the last few months.

  • Iain Brooks

    I really like the new bios systems. my bud bought a sandybridge board and they are leaps ahead of the older bios systems. This is a nice option for AMD lovers, but I wonder what percentage of sales these boards really get on the market against Sandybridge

  • Optix

    Good boards, but the new cpus are the main thing im waiting on. id say SLI and CFx are small markets. a new range of CPUs might make AMD competitive again. If they can match the 2600k they are onto a winner, but its a tall order.

  • Kalisti

    A lot of detail in this. I really do rate the X6 processors. I thought they would be pretty poor and my friend bought the 1090T and I wouldnt even know it wasn’t an intel chip. I suppose benchmarks highlight it more, but for gaming? I doubt anyone would know if someone changed their system without them looking.

  • k0rn

    Im excited to see the new CPU’s. Its a nice start, but its pretty uninspiring, apart from SLI support. and most people who want SLI will already have intel chipsets.

  • Headsintheclouds

    I bet this took some behind the scenes negotiations. Nvidia allowing AMD to use SLI.

    Good move however and nice new range of boards. Will be looking forward to the new range of processors.

  • Ned

    AMD have such a tough job really. Intel are dominating the CPU market. I do agree, the 1100T and 1090T are great products. for gaming they are perfect.

  • Brooke

    Asus make great boards, this is one of them. Sorry but im waiting for the new cpus before I even contemplate a new board. The current phenom X4 and X6 range doesnt appeal to me. im not a power user, but I dont see any reason yet to move to intel.

  • michael jones

    Finally a modern board that can do X16 sli, Intel can stick their thousand different socket types where they belong
