Pros: Quick and easy install. Replaced a bad MSI board with this and I was rather impressed with how easy the whole process went.

5 out of 5 eggsGreat Mobo

Pros: Up-gradable with 4 slots for ram, lots of sata ports, all around great mobo!

Cons: Bios setting boots the display off the pci slot first, headache cause i didnt realize this, my fault

Other Thoughts: got this for my first build, tryed pluging everything in and go, but i didnt have the driver installed for the video card, had to unplug Gpu, plug monitor into mobo, change bios to display from mobo, installed os, updated driver, chaned bios, it worked! i'm not complaining, just learning. i got this as a a diy combo for gaming, spent >$500 inc OS and Shipping, on par with PS4 and XBONE, I love newegg thank you so much!

4 out of 5 eggsThe motherboard that could

Pros: This little mobo is pretty great. It's one of the few AM3+ micro atx motherboard, and it looks outstanding.Its somewhat stable so that's really good. I have it paired with a FX-6300. I'm not overclocking yet.Integrated back up GPU which happens to be in use right now.

Cons: While this is a great motherboard theres a reason I gave it 4 eggs.
1. I had trouble booting from usb off any usb port. I had to barrow a friends DVD drive to save the day.
2. The off color sata cables. Why not spend maybe another 2 pennies and give us black ones?(Although this doesnt really bother most people, I have this board inside a 350D Windowed case, and that sticks out the most)
3. Theres 2 fan ports. 2. one for CPU and one for case.I knew this going in but still, what the POOP GIGABYTE.

Other Thoughts: Overall I'm fairly happy, other than having to now spend about 10$ on a fan extender and 4$ on a new sata cable for asthetic looks.Aside from the USB issues, I'm proud to say this is my board, and it's in my system.

4. Check for visible bent or broken pin(s) in the CPU itself (AMD CPU).

5. If you have an add-on video card installed, please check if the card requires additional powers 4, 6, or 8 Pin PCIE power.

5 out of 5 eggsAnother one, flawless victory.

Pros: This is pretty much the best cheap board I've ever bought... Tons of features for 65$~ Heatsink on the VRMs! Yay! And... Now? I've bought 5 of these so far and all are flawless to date! All rocking Phenom II X6's to FX 6300s! And I ordered another one today to plug in a Sempron and core unlock it! XP

Cons: Uuuh...Let's see... the SATA placement is a little awkward.. So is the IDE but.. Eh... It's still flawless.

Other Thoughts: Gigabyte knocked it out of the ballpark with this one.. This is my choice motherboard for all cheap budget builds... It's beyong perfect.

3 out of 5 eggsGreat board so far.... except....

Pros: Ports. All the ports. USB 3 header. Ram slots!

Cons: For the life of me, I CANNOT get this board to send out a 5.1 signal over HDMI. It always sees whatever is connected as stereo. Tried 15 different drivers with no luck. I popped in an older PCIe video card and poof, 5.1 audio. For now, my review stands at : DO NOT BUY FOR A MEDIA CENTER

Other Thoughts: Hopefully a driver / firmware update will come out, then this would be a 5 egg review, no questions.

Almost not worth mentioning, but the board is thin and flexible. Not a pro or con, just info.

5 out of 5 eggsAddendum: My board didn't die

Pros: I posted a review a couple below this one that my board died after 4 months... It turns out that the board is fine. I'm having power problems in my home office, probably brownouts. If I plug this computer into a voltage stabilizer (Opti UPS 1200 from this site), it boots up just fine every time.

It's possible that the board is being picky about power quality (most modern boards have a "power good" circuit) but that's not necessarily a bad thing.

Cons: None that I can think of at the moment. Great board overall, especially for a budget board.

Other Thoughts: Sorry for the erroneous review. The failure really was acting like a motherboard failure, because another motherboard was working. But with good power, this board also works fine.

5 out of 5 eggsHassel Free Install and Operation

Pros: Easy to install. Everything works. Can OC with bus speed change. Looks quality.

Cons: None.

Other Thoughts: Had a spare Athlon II X3 3.1GHz and decided to use it to upgrade my HTPC which had lost its sound when upgraded from XP to W7. This board was an absolute breeze to install and also a bargain. Am running @3.6GHz with a bus OC and DDR3 1600 RAM. Would buy again. Watched Gravity the other night & all is well. :)

5 out of 5 eggsSeemed like a good board

Pros: I thought this was the cause of some problems I was having in my build (It wasn't, turned out to be the CPU cooler of all things).

It seems like it'd be a good board.

Cons: None
