Weak 4+1 power phase holds back overclocking potential, but has Crossfire capability, so there's that. It looks cool, too - dark PCB and heatsinks. UEFI BIOS leaves a bit to be desired compared to higher-end boards, but it's actually not bad. At least it's UEFI.

A very good Motherboard for my first build, also the cheapest one I could find. Great quality, not flimsy feeling or anything. I would highly recommend this to anyone looking for a good starter MOBO. Only con is that the positioning of the SATA III plugs are right below the mounting points of the GPU, my GPU is long enough to cover the plugs right over. Im assuming i will run into this problem on most MOBO's but still. Also, no USB 3.0 headers :<. Was going to buy a PCIE header expansion card, but decided against it. The 990fx Extreme series is great. Going to buy the best one in the series. :D

Positives: It works very well. Not a lot of capacitors for the CPU, overclockers beware. It works, haven't had any non-user-induced issues.

Negatives: Not for overclocking. As I'm writing this the voltage shown on HWMonitor is bouncing from 1.264 to 1.256 rapidly. Not due to temps, everything is very cool right now. The clock rate on the CPU also fluctuates (for no apparent reason?) from time to time, again not due to temps. Due to the naive overclock, I messed up the thermal throttling and had to clear the CMOS, which seemed to fix it. Still, though. I'd prefer it a lot more if it had one less power phase for two or more capacitors.

Great board for starters. Features all the things needed to build a great gaming computer. The only complaint I have is that it doesn't have a USB 3.0 header. But i guess that's what you get when you are on a budget.

It has been running strong for the whole time i have had it.

Once again: Great board for anyone on a budget or just newbies.
