1 out of 5 eggswont replace

Pros: Nice motherboard if it worked all the time.

Cons: Had to RMA this soon after purchase they supposedly fixed the motherboard. I feel it has not worked correctly. Now I am having problems with the built in network and they want me to send it in to be check and fixed or replaced. REPLACE it don't make the customer wait 8-10 weeks for it to supposedly be fixed, back your product 100% and replace defective items. DON'T BUY GIGABYTE!!!

4 out of 5 eggsDecent board with a few quirks

Pros: Good looking, plenty of capability for a now older chipset.
USB 3.0 support seems to be quite good. I've even noticed some better response times on a couple of my old jump drives when connected to those ports.
BIOS is pretty straightforward and relatively easy to use with plenty of options. I have not yet tested the overclocking capability of the board since I'll need to replace a large case fan that is very annoying (bad bearing or something) and install additional fans before I attempt it.
The board size is a big plus for me. I do like having plenty of options available and best of all The PCI-E 16X slots are properly spaced. Meaning if you run a dual card setup, you're not wedging them together and having a ton of board space underneath them. This allows for much better airflow across the cards. This was something I had a hard time finding in other boards back when socket 1366 was more widely available and even now as well (but then again socket 1366 is getting a bit harder to come by due to the new socket 2011)
Dual-Bios option is very nice to have in case you end up with a failed flash. Definitely some peace of mind there in terms of bios upgrades.

Cons: The secondary PCI-E molex power port is in an awkward position that actually prevents me from plugging anything into it in my Antec Eleven Hundred. I'm not certain if a slimline style 4 pin molex adapter would work either. However I've used motherboards where in a Sli configuration a 4 pin molex was not needed to run them, let alone having to plug in two of them. Plus the location of the first one as well doesn't make for clean cable management either with power plug that shouldn't exactly be needed on a board this advanced.
I've had some issues with the onboard audio in Win7 x64. I use it via an optical connection to my Logitech Z5500 sound system, however windows notification sounds appear to be 'clipped' and there was serious sound distortion issues after a few hours of use. Updating the driver seems to have at least temporarily taken care of this. Also getting audio to properly play out of the optical audio port with the mfgr provided drivers is really a pain in the rear. It was a good idea to integrate an X-Fi on this but at least in my experience it's not been seamless. This seems to me at least to be more of a software issue than a hardware problem.
A major con which I missed in my research is the onboard SATA 3 controller. Seems to work fine as long as you are using single drives. My SATA 3 SSD Raid 0 array actually performed worse than they did on the SATA 2 ports. This appears to be an issue with the actual controller and not a fault of Gigabyte.

Other Thoughts: The Killer NIC card is an interesting bonus but seems more intrusive if you just wish to get up and running on a network and by default enables application level controls. It's also a shame that Windows 7 does not recognize the card directly. This could be remedied by slipstreaming the drivers however BigFoot does not have a silent install package for the drivers available for download nor do they have just plain unzippable driver package for those who have already performed the firmware upgrade as needed by the driver set.
All and all this is a good board. I have a SATA 3 traditional hard drive I use for data backup so I can at least still use the port and gain some benefit out of it. If you are looking for a RAID 0 solution using SATA 3 however, this will not be the board for you. I look forward to seeing how this thing overclocks.

3 out of 5 eggsGood Board, Fast

Pros: This is a good board, and is fast. Looks good. Sooo many pretty lights..... BIOS are good. Integrated sound is great but (see cons). USB 3.0 ports are fast fast fast.

Cons: Two issues I'm having with this board. 1) The "Netsh Winsock" hack with the bigfoot killer card is really starting to irk me. My iPad won't update unless I do this. 2) The sound card will occassionally make a popping sound like there is some interference. I say sound card because it happens when using either speakers or headphones. I did some research and other users found this may be a defect in the board. I have plenty of power from my AX 1200w, so I don't think it's that, though I do notice I hear it less when other electronics are off (like a fan or my other computers). Still under warranty, so I may try to omit the Bigfoot drivers, see if that fixes the iPad issue (even though this will require a complete resync of the iPad :/). If anyone has thoughts on how to fix either issue, I would be happy to hear them. Drivers were from Gigabyte site.

Other Thoughts: I think this is a manufacturing flaw in the Case, but I had an absolute BEAR of a time fitting this board in the HAF X. The Cards would not sit nicely in the case and lock into position while the i/o panel was lined up correctly. Frustrating, as I spent a lot of money on this machine, but as I think it's a case issue, didn't dock a star. Ironic that my cheaper machine worked flawlessly, but that's usually how it goes I suppose.

Will repost if I find anything out with resolving these issues.

5 out of 5 eggs

Pros: works perfect.. over the years I've upgraded my Gigabyte 58xud7 so when i saw this board on sale it was time to use all the leftover parts and WOW

Cons: This board works so well that I may need to swap it with one in my Gaming tower :)

Other Thoughts: Only load what you need then go to the manufacture site and load the latest drivers & software my SSD loaded windows7 ultimate in 8 min and the SSD got faster after the latest drivers........
my ud7 only has 2, 3.0 usb ports this board gives me 6, 3.0 usb ports and runs better power to the cpu& vid cards

5 out of 5 eggsBetter than Other x58 Boards!

Pros: This board performs very well. Everything was correctly working when I got it new, and it still is. This board overclocks much better than other x58 boards I have owned. Right now my 980X is sitting at 4.3Ghz (I've ran it up to 4.6Ghz on this board) and its cooled by an h100.

The creative audio on here really is superior to the ALC chipsets. It sound pretty good, the driver and utility is amazing. It even has an ASIO driver and for audio production work and has an audio production mode in the utility. The audio utility has 3 modes, one for gaming, one for audio production, and one for home theater entertainment. The gaming audio mode is pretty awesome for games and gives a really cool perception of 3d.
Overall the audio is good, however it is noisy, unlike my rampage III formula's alc 889 chipset, which was perfectly noiseless. However that board had a few issues so I sent it in to get it fixed and got this board. I will put that rampage into a second build when I get it back.

Cons: No firewire ports (ieee 13904)
Intel Lan would be much better than Killer Lan (important if installing OS X)

The sound chipset is not as good as advertised. It is noisy, and when you connect the sound to a sound system it makes a whinny noise and gets annoying so i have to put the volume down on the sound system when not using audio. This happens on my particular board, but who knows maybe other people don't have this issue. Some boards turn out better than others. Although this may be cause by something else on the motherboard. I have a Zoom H4n and when I connect it to use as an audio interface it also makes the same noise. The noise disappears when I disconnect the usb chord from the zoom. I bought a pci-e firewire card to try connecting my presonus audio interface. I hope the noise will not be passed on to the interface.

Also if you were to install OS X your audio would not work, so going with a board with alc chipset is better in that case, or getting an audio interface...

Other Thoughts: Overall this board is very good. I would be absolutely happy if it had firewire, intel lan, and the audio was not noisy.

However even with all of this I still love the board as is and i'm coping with all the issues.

5 out of 5 eggsawesomeness

Pros: Big foot is fast for an on-board inc. I did a little over kill on the I7 960 for the of with air cooling. Easy oc functions and that there is different stages for the beginners and the advance for Ur hardcore ocers.

Cons: Ran into a problem with startup. Troubleshoot. I found out the if the ram is not in the right slot it will not post. So u must read manual very , and I mean very carefully about ram positioning. It will tell which ones has to be used. And or how many sticks u r using.

Other Thoughts: My setup
I7 960 @ 3.2ghz overclocking @ 4.25ghz
Gtx 580 3072g
Corsair vengeance tri channel 12 gb (3*4gb)
We cavier black 2tb
Cm v8 CPU cooler
Asus blu-ray burner
Aerosol strike x st case
Cm silent pro gold 1200w
Gigabyte g1 assassin x58 mono.

Feel free to rate and/or look at my setup. @ modrigs.com @ evga.com.

5 out of 5 eggsI LOVE IT!

Pros: I am going to give five eggs eventhough I knew before buying this board that the Marvell 6 gb/s ports do not work....and never will! The 6 SATA2 ports by Intel do; and very well. With that, the G1 Assassin is still really a great board! AND it looks cool too. I love these themed boards! I really do. so, as a computer builder for work, I would highly recommend this board to my customers who are going to keep using the 1366 socket. really, the 1366 socket is still a current and great series for the next 2yrs

Cons: if SATA3 is what you really want, then buy the new x79 series. however, do not get the G1 Assassin 2 becuase of the danger that it still can catch on fire! anyway, the Intel SATA2 ports just simply ROCK!!! the SATA3 ports do not work and they NEVER will. there really is no point in trying to fix them on Gigabyte's side. oh well. still a awesome board, however!

Other Thoughts: I have the EVGA CLASSIFIED LIMITED EDITION x58 motherboard. that was the best x58 board ever made! if you can find one, I would suggest you buy it! the G1 Assassin A1 is second on that list.

1 out of 5 eggsa nightmate!

Pros: Will never buy a gigabyte again I had the x58a-ud3r and swore by it so I bought the g1.assassin at first I was upset it did not fit in the level 10 gt case but in all fairness they do tell you this board is freaking huge and it is so I modded my case got it in everything booted up nice fast and clean then I started messing with the sound the creative sb x-fi on it over amped "hissing" sounds crackle and poping. first I tried to get in touch with creative HA what a joke that was there is no support zero nada nothing.. I then went and tried gigabyte support what a nightmare I called in let them know what was going on first tech seemed okay willing to help he said they would bring in a g1.assassin and see if they have the same issues he then asked me if I installed the newest drivers I said "yes" he then told me the size of the file 204mb I was looking at mine and seen mine was 208mb so thats when more questions started to arise

Cons: I asked him what version the newest driver was he said 6.0.01.1327 the ones on the MB disc was 6.0.1.1327 as you can see its very close to being the same another thing that grabbed my attention was the dates on these drivers 6.0.01.1327 from there website dates 02/15/2011 the ones on the disc date 12/1/2010 the ones from the disc install when I uninstall these drivers and try to install the ones from the site it says it cannot find any creative hardware on my computer... they just simply don't understand the issue if you are going to sell in the USA have a support team that can 1. speak the language 2. understand the language nothing is more irritating than to spend 20 minutes on the phone telling them what is going on and they simply don't understand you

Other Thoughts: all I wanted to know was this a known issue with the board have they had calls in the past about this or is this a "RMA" board and now its turned into a huge mess... I will be avoiding gigabyte like the plague for now on which I am sad about because I love there motherboards but there customer service killed it for me

5 out of 5 eggs

Pros: Very nice looking board, things are easy to get to. Had no problem getting it installed in my Cooler Master HAF X RC-942-KKN1 Tower. It actually looks kind of small in it. The extension piece for the front panel is pretty nice. I found the board looks very nice. The bridges and heat syncs are attractive. Havn’t played with the OC option but looking forward to it.

Cons: Was having significant problems with the onboard Bigfoot Network Killer Ethernet port. I was unable to Access most Secure websites, could not access ITUNES store, and, not that I use it normally, IE9 kept crashing. At first I did not expect the Ethernet, but then after performing a couple of ‘NETSH WINSOCK RESET’ s when I would reboot I would receive a ‘LSP not mapped correctly would you like to remap’ if you hit yes the problem would continue, if you hit no it went away. After some research I found that wireless versions of the BIGFOOT network cards have the same issue. It being a 1GPS card was a big selling point, but I just jacked my old expansion card out of my old computer (also 1gps).

Oh and the stupid apps that come with the motherboard stink. Zynga is already uninstalled.

Other Thoughts: Really nice.
