Gigabyte G1.Assassin X58 review

An army flavoured enthusiast board for military-mad billionaires

Our Verdict

A pumped up grunt of a board - power mad, unjustifiable and a waste of fiscal resources.


  • High performance
  • 'Specialist' visual appeal


  • Hugely overpriced
  • No incentive to ignore Sandy Bridge

The market for top-of-the-line X58 boards should have dried up with the release of the Sandy Bridge chips, but the Gigabyte G1.Assassin X58 board is looking to get people excited again.

The latest Intel Sandy Bridge chips have dominated CPU-related column inches, for better or for worse, since their release early last month.

That said, it's still the Gulftown chips and accompanying X58 chipsets that sit atop the entire Intel range though, for now at least.

The Intel Core i7 990X Extreme Edition is theoretically Intel's fastest production chip, and that leaves enthusiasts in a quandary.

Stick with the X58 platform and buy the best right now, or wait for the Sandy bridge SATA issues to be resolved and invest in formidable new technology with an eye on a Sandy Bridge hexcore?

I certainly know how Gigabyte would answer that question. 'Live in the now, man! What's money anyway? You can't take it with you!' That's what they'd tell us, in a voice almost as loud as the X58-based G1.Assassin's visual stylings.

Priced at over £400, this is very much an enthusiast's mobo solution. In amongst the cooling bits modeled on ammo clips, the Gigabyte G1.Assassin sports two PCI-E x16 and two x8 slots, so sexy crossfire GPU foursomes are on the menu.

There's also triple channel DDR3 memory supporting up to 24GB at up to 2000MHz. It's USB 3.0 and SATA 6Gbps friendly, as you'd expect for the price.

You'd also expect a bit more, wouldn't you?

Marketing Information

The GIGABYTE Ultra Durable 3 design features twice the copper for both the power and ground layers of the PCB, dramatically lowering system temperature by efficiently spreading heat from critical areas of the motherboard (such as the CPU power zone) throughout the entire PCB. GIGABYTE's Ultra Durable 3 also lowers the PCB impedance by 50%, which helps to reduce electrical waste and further lowers component temperatures. A 2x Copper layer design also provides improved signal quality and lower EMI (Electromagnetic Interference), providing better system stability and allowing for greater margins for overclocking.
