Price History (Excluding Tax & Combo Deals) History:


from completed build BlackIce (First Build)

Looks wonderful, works great. Has plenty of ports and whatnot. Was completely plug-and-play on my Linux system. Had to push it up a bit against the I/O shield to get the screws lined up. The BIOS has lots of settings and is pretty. 10/10.

from completed build KONQUER (the Budget)

Only 4 stars because of the locations of the chassis fan connectors.

from completed build Olivia

ASUS, in opinion, is the premiere motherboard and this board had everything I needed at the time, USB 3.0 header on a AM3+ was not common a few years ago, and I am very pleased with this board. The onboard RAID is a bit simplistic but so far no issue.

from completed build well, she is finished for now....

Loads of settings and..... stuff that i've no idea what happens should I touch it lol. but a nice mouse driven bios, made my noobness able to tune up my ram and have a straight 3.5ghz boot. I used the Asus AI suite app to overclock further.

from completed build AMD 8 Core Gaming PC

Easy to install, and plenty of different connection points for various things.

from completed build KONQUERER

Only 4 stars because of the locations of the chassis fan connectors.

from completed build Gunpowder & Lead

I've read really good reviews on this board, I really liked the colors, and I frequently see it paired with the FX-8350. I have zero complaints.
