5 out of 5 eggsThis Board is Impressive!

Pros: Great board, extreemly stable. Using with Patriot Extreme Performance 2GB (2 x 1GB) DDR3 SDRAM DDR3 1333 (PC3 10666) Memory (1.5v) and Intel Quad Q9450 Yorkfield 2.66GHz 12MB L2 Cache 95W 45nm Quad-Core Processor and a single HD4870 video card. Added a DuOrb cooler (fits good, I was able to install without removing rear copper heat-sink!), just make sure your RAM is not to tall. I have overclocked the Proc to 3.25Ghz and the RAM to 1366 with no problems, and I am not done yet, as I have not yet had to adjust the voltages. Windows XP flies open and is very resposive. Games are very fast and have high FPS on my 22" LCD. I like that that BIOS will recover and load privious settings if you make a bad choice while overclocking.

I will have to upgrade my current 500W power supply before cooking my feet with DUAL HD4870x2 cards ;-)

Cons: Most expensive mother board I have every purchassed! But the overclocking makes it a good trade off. I am running a RAID 5 with four 500GB hard drives, so most of my SATA connectors are used up. With both the Intel Matrix on-board RAID (six yellow SATA connectors) and the Gigabyte on-board RAID (two purple SATA connectors) the boot up processess takes longer to get through the BIOS then to bring up Windows. I have the Gigabyte on-board SATA connectors set up for the eSATA so they scan for a short while before continuing. For the price, Firewire 800 should be the standard. The Dynamic Energy Saver Advanced software gives an error and won't work if overclocking. I would love more explination on BIOS tweeking settings. There is not a lot of documintation. However, if when tweeking the BIOS, you make a bad choice, the system automatically reboots and reverts to the last settings. This makes overclocking choices painless.

Other Thoughts: DDR3 price to performance may not be worth it. I am waiting to buy more and faster memory when the price comes down and lower latency RAM comes out at faster speeds. Some benchmarks show more improvement at lower latency then running DDR3 at faster clock speeds. When I go to 64 bit OS, I want to pack 8GB of fast memory and see how it runs.

5 out of 5 eggsGreat Motherboard

Pros: This is my forth Gigabyte MB. They overclock very well and they are stable.

Cons: Their support sucks **** through a straw but the quality of their motherboards makes up for it.

Other Thoughts: If you are a novice, don't expect support.

5 out of 5 eggsGreat Board

Pros: Crazy Cool Heatsink for over clocking, plenty of bios backups, great craftsmanship of the board.

Cons: RAM DIMMS are a little too close to the CPU if you use an after market cooler. I had to the OCZ reaper memory with the heat spreader& a tuniq tower. (I had to use dimm slots 2 & 4 instead of 1&3) The Heat sink of the reaper memory contacts the grill of the tower, but its not stressing either.

I still gave it 5 eggs as the ram and aftermarket cooling was sort of a bad combination and my choice. Wouldn't want your ram far from the NB anyway, particularly DDR 1800 =P.

One more thing, don't try and use 8GB's of DDR3 with this, it doesn't work.... yet. - Maybe if you find a Quad Channel 8gb kit, but even then I think the controllers will have to adjust timing to acomodate the large amount of ram.

Other Thoughts: If you use a Tuniq Tower with the crazy cool heat sink, mount as you normally would, but be prepared to have to bare down the screws quite a but to be able to thread it.

I actually took the springs off 2 screws and put them in place, leaving two springs on opposite corner screws. after I seated the springed screws I removed the remaining non-springed screws; put the springs back on and it works very well.

Having done that the heatsink and the base plate of the tuniq tower make this board fat, I was still able to screw the board into the case's frame confortably though... tight fit.

4 out of 5 eggs

Pros: Overall a really good card with good features. The onboard audio on this card is amazing. Especially paired with a BD drive.

Cons: 2 of the 4 memory slots are bad and cause BSODs and failures in Memtest. I switched to the other 2 slots and no problem. I would RMA the board if it wasn't in such a small case.

5 out of 5 eggsA+

Pros: Installation was simple. Didn't have any trouble with the Crazy Cool plate - was not in the way of anything (with stock or my after-market cooler). XMP profile works great(1800Mhz DDR3 - wow!).

Cons: Had trouble getting board to recognize second stick of memory. Kept trying, and it finally took it (1x2GB Patriot Viper DDR3 1800).

Other Thoughts: I wish all installs would yield these results.

5 out of 5 eggsGreat motherboard

Pros: This is one of the best motherboards I have ever installed. It works great. I have 2 RAID 0 arrays (2 x Raptor 74GB for OS WinVista64ultimate and 2 x WD Caviar 500GB for data) and it was extremely easy to set up the RAID arrays. Nice colorful lights. Looks great in my Armor+

Cons: The crazycool plate at the bottom of the mobo can be tricky when using a Zalman CNPS9700 cooler. In order to be able to make it work I had to purchase a Zalman ZM-CS1 support. That made the trick.

Other Thoughts: My rig: Thermaltake Armor+ VH6000BWS - Intel Q9550 - Corsair CMPSU-1000HX - OCZ Reaper 1333 4GB - 2 x MSI 3870 in Crossfire - 2x Raptor 74GB in RAID 0 - 2x WD Caviar 500GB in RAID 0

4 out of 5 eggsExcellent Mobo

Pros: Ordered this mobo after I had a huge debacle with EVGA's 790i Ultra. Went through 2 of those boards before I settled on this board. I have owned Gigabyte boards in the past and they have served me well, so I figured I would give this one a try. The manual for the board was very detailed (read thick) and had lots of diagrams and pictures. Good for those first timers out there. Popped the board in my case, fired it up and off it went. No problems. I will have to say, this was one of the easiest boards to seat RAM in that I have ever owned. The RAM popped right in and actually latched itself in place. Usually you have to push and manually close the locks. Not here. Gentle push into the DIMMs and they locked right in.

Cons: I chose not to use the CrazyCool plate because the mounting screws would have prevented me from mounted the heatsink for my CPU. I also could not get 2x2GB DDR3 modules to work in this board. I went through 4 different ones (Patriot 1600, OCZ Reaper 1333/1600 and Corsair 1800 Dominator) before I finally grabbed a 2x1GB kit. I used the pink slots as suggested, but no dice for those 4 2x2GB modules. They couldn't have all been bad, infact the Dominators weren't, because they work just fine in another rig of mine (Q9450, Asus Striker II).

Other Thoughts: I am using this mobo in a Thermaltake Armor case, 850W CoolMax, Intel Q9550, 2x1GB Corsair 1333, GTX 280, X-fi Fatality, 300GB VRaptor (320GB,500GB,1TB backup drives).

3 out of 5 eggsBad CPU Socket

Pros: Extremely fast, according to research, THE fastest mobo out there right now.

Cons: First one arrived DOA. Contacted GigaByte tech support, they stated it was possibly a bad socket or bad CPU. Had CPU tested, and it was fine, narrowing it down to the mobo. I guess quality control is slipping for even the best manufacturers. Sent back to Newegg for RMA.

Other Thoughts: Got new mobo, and it is stable. Has more settings than most ppl will know what to do with.

5 out of 5 eggsI Love This Board

Pros: Bags of Features, Very Well Built, Nice Cooling

Cons: About the only thing it doesn't have is onboard video, but who uses that?

It might come in handy one day though

Other Thoughts: Gigabyte GA-X48T-DQ6, Intel Core 2 Quad Q9550, OCZ Platinum 4GB (2x2GB) DDR3 2000, FSP Group Everest 1010 1000W

1 out of 5 eggsNot so AWESOMENESS

Pros: was a great board while it lasted

Cons: F5 Bios victim

Other Thoughts: I would like to thank gigabyte for releasing the Corrupt F5 bios that killed this board. It now sits in my cube for decoration while i wait to RMA it.
