-Good expansion slot layout
-Firewire and mini firewire
-No esata
-4pin power not at the top
-USB headers not at the bottom
This is a pretty good board. The only things I would really change are mentioned above. I don't like cables running to the middle of the board. Otherwise, I have not issues running a Athlon II x4 635 and 4gb of G.Skill PC2-8000 DIMMS.

Experience: 15 Days
 Verified Owner
Good quality, fair price, lots of bang for the buck
DDR2 only
This may not have all the bells and whistles, but for the price you pay, you cant get any better especially if you have $15 ddr2 ram lying around!

Go with DDR3 when the price drops (ie not this board)

Experience: 5 Months
 Verified Owner
Alot of USB ports, good feature set, plenty of expansion.
Works fine. I initially gave it a bad review because it failed after two months and 23 days. It started giving POST beep codes for the vid card.

Turns out it was one module of my memory that was causing it.

Lots of PCI-e slots, 8 pin 12v motherboard power, unlocks extra cores (YMMV)
8 pin 12v power is in a bad location. CPU are is cramped when using a big HSF.
Got this board in May and I got rev 2.1. I was able to unlock 2 cores on my CPU to give me a quad core. Board layout is good (except for the 8 pin 12v power) and there are 2xPWM headers on this board. The CPU area is a little tight for larger coolers and I have to rest my CPU fan on-top of either my RAM or my NB (Scythe Ninja rev2). Overall a good board, especially for the price!

Experience: 4 Months
 Verified Owner
Decent lay out, room for upgrades, nice CPU support
no DDR3 support? Heatsinks are a pain to put in (board heatsink rather close)
No complaints aside from trying to mount an after market CPU cooler was a pain in the arse, as the bridge cooler was too close to allow for easy attachment. 16 gb or ram support is a nice bonus, as is 6 SATA ports, and a plethora of usb ports. Nice bang for buck, good base for a budget gaming build, though would like to see something in this range with DDR3 and dual PCI-E support.

Experience: 3 Months
-reliable brand
-good warranty
-doesn't have esata
Apart from not having esata, it is good board. What separates this board from some of the others is that it doesn't have integrated graphics. This is good if you plan on buying a discrete graphics card. If you use a lot of pci-e slots this is the board for you.

Experience: 1 Days
gigabyte product .... uses both AM2, Am2+ and AM3 CPUs
none at all except I would have liked more PCI slots
Very good. Front audio connector is all the way at the back of the Mobo however
Decent BIOS....lots of hidden software on the driver disk. wish this mobo came with an overclocking utility however. Otherwise laid out very well.

Experience: 2 Days
 Verified Owner
Well built
Easy to use and install.
None so far.
I've built a computer with this motherboard and I have no complaints to make yet. The CPU installation and ram installation was easy as cake. Installing the GPU was not a problem and everything is fine. The only thing that lacks quality is the driver CD wich is really easy to intall but lacks a bit of nice visual.

Experience: 5 Days
 Verified Owner
AM2+ and AM3 support
Could have more usb expansion room
Solid design and excellent quality.
Great price, true value.
Flexible: AM2+ and AM3 support, Win 7 ready, overclocking made easy
Room for improvement: Could have more usb expansion room
Would buy again

I got a rev.2 board - SB710!
Full AM3 Phenom support
Hella USB ports
FireWire for $80 - wat!
Layout sucks
Heatsinks too small
I needed a cheap ATX board with DDR2 and support for the latest AM3 Phenoms. This fit the bill nicely. The one I received was revision 2.0, so it has the SB710 southbridge.
C&Q disables if you change the multiplier to overclock (I have a X2 550 Black Edition). I like to have my cake and eat it to, so I changed the CPU freq instead - got it up to 3.6ghz. Fan control is good, use SpeedFan to fully control the CPU and SYS1 fans.
No issues with it except for the layout (8-pin connector, USB headers, SATA ports) and the heatsinks are too small - they get mighty hot.

Specs: X2 550, Katana 3, 4GB A-DATA DDR2-800, HD 4850, WD6400AAKS, Seasonic SS-350ET.
