Price, Features, usb and sata 3.0, Crossfire support, lots of usb connecters on back panel etc
Non so far!
Wasn't looking for all the bells and whistles of the high end boards, but wanted usb and sata 3.0. this is the first Gigabyte board I've used. Bought it to use in my wifes work comp, she was still using an old pentium 3 Dell 7 years old so this was a big improvement. I like the lay-out of the board and there's more than enough perifials for her needs for some time to come. The price was well within her budget and the quality of the board seems solid I've allways bought Asus boards so I was glad I had a chance to be able to try this out. Great board for a budget build.
Would buy again if needed.

Experience: 2 Months


USB 3.0, fairly easy for a inexperienced builder to use
None so far.
This is just a solid mother board, it doesn't have a whole lot of fancy features but most people don't use those anyways. I used it to build a PC for my friend who's never built before and he had no problems figuring out where everything went. Board layout is logical and it's been performing quite well for several months. I would recommend this to others.

Experience: 4 Days


Reliable, SATA3, USB3, lots of SATA ports
None that I can think of
I've started to use more and more Gigabyte boards in the systems I build because I find they add more features to their boards than the competitors. Lots of SATA ports, USB ports and almost always dual Gigabit LAN ports.

This is an ideal board for a casual gamer/office system. Definitely recommended.

Experience: 5 Days


Cheap Price for many features
4 Ram Slots
This is a great board that supports SATA and USB 3 for a cheap price. I mainly bought it because it was fully Hackintoshable but it runs Windows 7 pretty well too. Its very customizable with plenty of slots.

One thing I really love are all the Gigabyte features. One I really love is the 2x increased speeds of charging time for iPod devices.

My bios was F9

Experience: 30 Days


SPDIF output, USB3.0
Not the cheapest, USB 3.0 bandwidth issues
This is a great motherboard and includes nice USB 3.0 ports. However, if you want to use a USB3.0 device, make sure you don't use crossfire or SLi as this motherboard will reroute the juice from both PCI-E slots.

Experience: 1 Weeks


Price, Performance, build quality, USB 3.0 and Sata3 compatibility
Crippled Crossfire performance(only 1 16x PCI-E slot), RAM slots a bit close to the CPU so depending on the height of the ram(G.Skill ripjaws) it may obstruct some after-market HSF's (although you can just rotate the orientation of the fan).
Overall an excellent motherboard with great performance and little flaws. Perfect for the casual user as it supports i5 and i7 socket 1156 cpu or a gamer that does not plan on going Crossfire with their video cards.

The board supports USB3.0 and SATA 3 compliant devices so it is future proof when those devices start becoming more common.

Experience: 1 Months


- Should be a rock solid motherboard with high overclocking potential
- Supports USB 3.0, as well as SATA 3
- If you're looking for a high overclock, this is not the board to get
- Unable to do SLI, and very limited on crossfire since one PCIe is 4x only.
This motherboard has the P55 chipset, so for the general user and even the casual gamer it does what it's supposed to do very well. The problem is that if you try to push this board it might not react too well to excessive stress.

I had to RMA this board because something suddenly blew out and the computer wouldn't even post after that. Now that I think about it though, I may have just been unlucky with the board, as its generally received good reviews and high overclockability from other people. Just be careful not to push it too hard as it lacks the proper cooling pieces to really save the board if it overheats.

Pricewise, though, it is one of the cheapest P55 boards I could find, and gigabyte should be a pretty reliable brand.

Experience: 6 Months


-Great Value for the money
-Blue PCB
-VRM's make squealing noise when voltage is w 1.3 or greater and cpu is at load.
-the SATA ports
It's a great buy if you plan on doing mild overclocks in a case that has no window. The blue PCB mixed with my noctua fans make my computer's inside look like barf.

Experience: 1 Months


- works great
- none so far
I use this with the i5 750 with 4gb of RAM and 5850 radeon video card. I have 2 ssd's in raid 0 and 2 sata hdd's. I have had no problems so far. Easy installation.

Experience: 2 Weeks


Good quality, easy to overclock CPU, well priced, has SATA3 and USB3.0 capabilities.
PCI Express slot gets crippled when using SATA3 / USB3.0
Got this motherboard recently at a great price. It has a lot of features and I was able to overclock my Intel core i5 750 quite easily. Everything seems to be running stable. Too bad when you use SATA3 or USB3.0,the PCI Express slot gets crippled.

Features [ Edit | History ]
