Gigabyte G1.Assassin X58 Motherboard Review

24 thumbs up

Both gamers and hardware enthusiasts can appreciate a good looking motherboard. Here, we find the G1 Assassin sporting a black and green theme, a first for a Gigabyte product.

There are four green PCI Express x16 slots on the G1 Assassin. For those with multiple videocard systems, this board is double spaced in order to support the installation of dual slot graphics cards. Dual card setups should make use of the first and third PCIe x16 slot, leaving the second slot empty to allow for increased airflow. Additionally, the board can handle up to three NVIDIA videocards in Tri-SLI, or up to four ATI cards for Quad-CrossFire. 

Also, one of the things we noticed right away was the lack of onboard power and reset buttons on the G1 Assassin. Every high end board we've looked at over the last several years has offered these buttons. So it is a bit strange to omit.

As with all X58 boards, this one has six memory DIMM slots. Install memory on the green ones first, and then the black slots once you get another kit. The board supports memory speeds up to 2200 MHz, with a total capacity of 24 GB.

"Excellent review, its one heck of a motherboard, and I love its design. It is what it is and it has its purpose even with Sandy Bridge out. Now, a word to Gigabyte, you guys have to stop with the UD name branding, UD7, UD5, UD4, UD3, UD3B, UD3B-A , this is nuts. The naming scheme has got to go. Asus has the Rampage line, Crosshair, Sabertooth, WS Revolution,all recognizable and people know what they stand for. Stop putting out so many boards.'

The product is amazing, what impresses me the most is an integrated Creative Audio 7.1 Soundchip, and the Bigfoot killer network card, those are little perks that save you space on the board since you don't have to add external cards, the design is awesome, especially for a themed rig but the $459 price tag is so daunting

It confuses me why companies like Gigabyte, EVGA and Asus release multiple motherboards within the $400-$600ish price range, it seem's like once you break about $300 on a motherboard you entering hardcore enthusiast territory, so each company should have 1 hardcore enthusiast board because an enthusiast mean someone interested in one particular subject or category and that mean's they want the best of the best so I'd imagine that the low end "enthusiast boards" don't sell that well

Great review, Gigabyte is really kicking some butt with this board. I love the green and black color scheme. Could you imagine a nice black case with the interior painted to match this board :)

Awesome one guys! Gigabyte makes some great ones :) price is meh...

I never thought I'd see the day. A Bigfoot NIC on a motherboard (the Creative Sound Blaster X-Fi integrated I'm not so sure about) Thank you Gigaybte for being the first to make this happen!

Anyways, this seems like a good board... I'm sure LGA1366 users will be pleased by this godsend of a motherboard.

$460 bucks at Newegg. Wow! I'll stick to Sandy Bridge. I can't afford to spend like this for just a Mainboard, no matter how nice it is.

Thanks for the review , even though I would not be considering a board such as this The G1 Assassin Gigabyte board could be the ultimate mainboard upgrade for some espesically the bigoot NIC that 's intergrated .I like how you test and explain the actual power draw tests at the outlet [always did] esp when other comaprisons of performance are pretty close with other benches the GB G1 Assassin.seems a bit more efficient to me

big performance & big bucks $460 ?? yeowzers!

Finally had time to sit down and read through the review. Very thorough and I especially liked the benchmark showcasing the network card. I always wondered how efficient it could be compared to their claims and that shed some light onto the subject. I agree with a lot of the others that say go for the Z68 or just wait for the next big Intel release instead; the pricing is just to much too invest into.

Thanx for the review. the board looks awesome, but while the bigfoot nic is nice, I have almost the same throughput with the dual nic's in my X58 UD5. (that is one of the nice things about this board, the abillity to chain the nic's together), and  who uses UDP anyway?
