The ASUS Sabertooth 990FX board is feature rich, well designed and built, and makes a great backbone to any high-end AMD build.
Fully supporting Windows 8, AMD Crossfire, Nvidia SLI, and the latest AM3+ FX processors, this board has more than enough power to go around.
I have actually bought three of these boards, two of the R2.0 versions and a single R2.0/GEN3 (with PCIe 3.0), each one has performed flawlessly. I have been using ASUS boards for all of my personal builds for a long time, and there is a good reason for that, quality. They work great, and in the rare case an issue may arise, the support has always been there and the issue corrected. However I have yet to have any issues come up on these Sabertooth boards.
This board sits as the backbone of high-end gaming system, with all of it's SATA ports saturated, running a hybrid dual-GPU setup, 16GB of RAM, and an overclocked FX Vishera processor. I have yet to find a task it can't handle, especially when you plug other high-end hardware into it.
The board has a great deal of on-board temperature monitoring, and this is one of the reasons I went with the Sabertooth, I have an OCD for monitoring my system very closely. I take very good care of my hardware. Using AIDA64 to monitor all of temperature, voltage, and fan speed sensors in the system.
The UEFI is great, as with many other ASUS boards. It's a fantastic overclocker. There is more than enough PCIe, SATA, and USB connectivity. The board is well laid out and designed. It stays cool thanks to that CeraM!X coating. It also looks pretty damn good sitting in any build.
This is, by far, one of the best AMD based boards for the AM3+ platform in my opinion. The quality and features that you get at this price point are amazing. This board can handle just about anything you throw at it. You plug quality high-end hardware into it and it will fill even the most demanding gaming needs. I would, and do, recommend it to anyone looking for great quality and features at a great price, especially for gaming.
This model has no PCIe 3.0 support, but for now, it's not necessary.
Hardware used to test these boards.
AMD FX-8350 OC @ 4.3GHz (Cooled by Thermaltake Frio / 2x fans push-pull)
16GB A-Data 1600 XPG Gaming Series DDR3
XFX Radeon HD 7970 3GB Black Edition
EVGA GT 640 Dedicated PhysX (Hybridize)
Corsair HX850W Pro Series PSU
1x Seagate 600 Series 240B SSD Boot/OS
With all of that plugged into this Sabertooth motherboard, it performs flawlessly. High end gaming (Battlefield 3 and 4, Metro Last Light, Tomb Raider, Bioshock Infinite, Diablo III, Saints Row 4, and countless others), live streaming to Twitch via OBS, recording via Fraps, this board does not skip a beat.
I have overclocked my FX-8350 to 4.7GHz very easily on this board, however backed it down to 4.3GHz to maintain long term stability and maintain lower operational temperatures on air cooling. I have also overclocked one other 8350 to 4.5GHz and an FX-8320 to 4.1GHz, all on these Sabertooth boards.
I also have all of the SATA 6 channels used in my personal system, with 1x SSD, 2x optical, and 5x HDD's. No problems, no slow downs, no bottlenecks.
There really are not enough good things I can say about the ASUS Sabertooth 990FX boards. If you're looking for a high-end high quality motherboard, this Sabertooth 990FX R2.0 is a fantastic choice. Gaming, broadcasting, editing, recording, it can handle it all if you couple it with other good hardware. It really is that simple.
