Gigabyte G1 Assassin Review

Introduction and Technical Specifications

Gigabyte G1 Assassin


With the LGA1366 socket being relatively old compared to it's LGA115x siblings, the X58 boards have been a little thinner on the ground as manufacturers have brought us P55 and then P67 based motherboards.

We've seen a few minor revisions to include some of the 333 feature-set, or tweak the odd thing here and there, but wholly new boards have been somewhat sparse.

Gigabyte have been beavering away on a new range of motherboards, the G1-Killer series. This consists of three models at varying price-ranges, the G1.Assassin, the G1.Sniper and the G1.Guerilla. Today we've got the full-fat, fully featured, top of the range G1.Assassin that comes complete with everything but the kitchen sink. There probably is a kitchen sink in the box somewhere.

Let's let Henry Kao, Gigabytes Senior VP of R&D explain :

“GIGABYTE is thrilled to be able to introduce the world’s first motherboard series designed solely for elite gamers. The G1-Killer series features the industry’s most advanced hardware and software solutions from Creative and Bigfoot Networks onboard as well as the top-notch quality and durability users have come to expect from GIGABYTE. So, lock and load gamers, the GIGABYTE G1-Killer series motherboards deliver a gaming experience unlike any other.”

A glance at the technical specs lends much weight to his claims, so without further ado.

Technical Specifications

There is little debate that the Assassin has all that you could desire. If you've got a checklist of features you want to get in return for your investment then this has all of them ticked.

Super Sight

Super Hearing

Super Speed

Super Shield

4-way CrossFireX™ and 3-SLI™

Onboard Creative Soundblaster X-Fi Digital Audio Processor (20K2)

Bigfoot Networks Killer™ E2100 Game Networking Platform

Locked and Loaded Heatpipe Design


X-Fi Xtreme Fidelity™

Front Access Control Panel with OC button

5 Smart Fan Connectors


EAX® AHD 5.0™

SATA 3.0 (6Gbps), USB 3.0 and 3x USB Power

GIGABYTE Ultra Durable™ 3


Dolby® Digital Live


Maximum CPU Power Delivery


DTS™ Connect


Dual CPU Power


Front Audio Headphone Amplifier


Driver MOSFETs


Nichicon High-end Audio Capacitors



These features make their way to all three models exception the G1.Guerilla which has the Creative X-Fi software rather than a dedicated audio chip and the Assassin is the only model that supports Quad-GPU with the Sniper and Guerilla being triple GPU. Although the Assassin is ATX-XL to gain that extra card slot so if you've got a more modest tower then you would have to pick the Sniper to get the same features as we have today, minus the fourth PCIe socket obviously.

Anyway, we have the ATX-XL board in our hands and a suitably large case so let's take a look shall we.

It's been a while since we've seen a new X58 motherboard, and Gigabyte have just solved that with one of the highest spec models we've ever seen. The Assassin.

Great review, nice to see x58 stuff. I'm sick to death of seeing sandy bridge reviews and all its problems. Not sure about the price though seen it on various sites for around £450. Looking forward to seeing reviews of the cheaper Sniper & Guerilla boards.

Love the Assassin build videos watched them all multiple timesQuote

21-02-2011, 06:44:26

The board is immense so the price fits it quite right. I would have anything against if it would be cheaper so I could replace my ep43 ds3l with it Quote

21-02-2011, 08:08:51

i was looking forward to this review fella, and you didn't let us down - that board is a beastQuote

21-02-2011, 08:41:52

Looks fantastic.

As for P67, it's still a viable option for noobs, I hope. Especially if we don't use the S2 ports.Quote

21-02-2011, 08:44:39

Silly Magazine heatsink (IMHO) or not, this board is indeed a beast and well worth the money, if you can afford it

I missed out on X58 and went strait from 775 and P45 to P67 and 1155 but if I hadn't done that I probably would have gone for this board.Quote

That rig hits my sweet spot in so many ways. First its pretty, its mean, its lean, and its black with green. Put it on the runway. The benchmarks were what I was waiting to see and I was happily grinning to see 'em, very nice. I mean, being able to run any of my games at those settings, with those framerates... that's LAN intimidating, friend smashing, and giggling like a maniac fun. The onboard sound was the final kicker for me. That just saves you a couple hundred bucks to turn around for SSDs or the watercooling etc etc. About the only thing I'd do if I were lucky enuff to be able to afford such a monster would be the case. I'd be pondering, and have been pondering on what I'd do to make the case even more match what's inside. And then I realized... I'd distress the paintjob and make it look like its been thru "heck". I do like the case, and the color scheme all told is very nice... but a little bit of stressing done with some imagination would really bring out something .. "else"? hehe. just my humble opinion, its just the green is sooo bright. I would prefer it a tad muted. so.. picky picky. But, just dreaming anyway.Quote

Great review and indeed green team all the way. Although the case you used not mine style but that board looks friggin awesome.

Now I have a Q for ya TinyTom, what would you prefer, this gigabyte board or a EVGA classified board ?.

I`ll take your advise thoug a 970, a couple of dominators and some green stuff.Quote

21-02-2011, 09:53:03

If only i had the money. Can't wait to see ehat Gigabyte come up with the 1155!

Damn, that's one hefty price tag. I'd love to get it, but I'm too poor

Here's hoping the Sniper is affordable for me xDQuote

21-02-2011, 11:14:36

Great board and great review . Love the content that you were putting on YouTube aswell.Quote

21-02-2011, 12:09:57

Nice gear, nice review. I did a comparison. I know that rig'll eat multimedia, 3D animation and stuff. My test was for FPS today gaming AvP benchmark. 1920x1080p, i5 750 @ 4Ghz and 2 480's @ 850mhz the difference was 2-18 FPS i think. FPS gain was slower. I enjoy overclocking and when the PC buzz'd and froze

A good overclocker motherboard is necessary, the root of the computer.

+???? lots of points for that ASSASSIN G1

Thanks OC3D my overclocks are OC3D enhanced


21-02-2011, 12:56:18

If they removed the stanag mag and the network adaptor and put a standard one on too drop the price a bit I would be much more interested in it Quote

21-02-2011, 13:28:29

do want.Quote

21-02-2011, 17:22:06

Think stick to the rampage extreme 3 at that price point and spend my cash on the new priced dropped i7 970!Quote

21-02-2011, 23:03:51

Them Metro 2033 results are excellent. Is it tested with Advanced DOF?Quote

These are the AMP! Models dude. We think now the original 580 I had, had a faulty vapor chamber causing the fans to spin up.Quote

22-02-2011, 09:40:33

that is one hell of a price tag indeed... but when you take away the cost of a high end sound card off it..then its not looking so badQuote

Hi. Is the cards with personal custom fan settings to go with 900mhz core frequency or Zotac's standard? Thanks

Excellent scores and Crysis play well done

I'm surprised with CPU Crysis results as my temps are alot lower @4Ghz than BFBC 2 @3.8GhzQuote

For £450 it’s just an over hyped rip off, for that money you could get a 2600k and an asus p8p67 deluxe.Quote

It is quite a pricey mother board though You could get a rampage 3 with 970 for the same price of this with a 950 I know what Id choose. Is this motherboard worth it for how much more power its gives per cost I don't think does then again you have both boards so I cant really judge.Quote
