I bought the Gigabyte GA-965P-DQ6 more than 3 year ago at the end of 2006. It was a great motherboard at the time loaded with features and a perfect compliment to the then best CPU, the core 2 duo. The "DQ6" stands for "Durability Enhanced, 6-Quad Features" - which also includes the "S-Features". These features include:
* All solid state capacitors for longer lifetime
* Quad BIOS - four copies of the BIOS, two on flash rom, one on HD, one on CD
* Quad Cooling - four heatsinks for the motherboard chipset, Crazy Cool heatsink on the back
* Quad Triple phase - total of twelve power phases to deliver steadier power and current at lower temperatures
* Quad eSATA2 - four external Sata2 3Gb/sec ports for expandibility
* Quad Core Read - will support quad core processors
* Quad DDR2 slots - four DDR2 slots
* Silent-Pipe - chipset cooling without fans for low noise systems
* Speed - extensive overclocking / tweaking settings and utilities
* Smart - easy flashing from Windows or even the BIOS
* Safe - dual bios, s.m.a.r.t. support for HD's, saved BIOS settings and health monitoring
When I first took the DQ6 out of the box, the layout was very clean and centers around the solid capacitors, a heatpipe cooling system running through 4 strapping heatsinks, and a wealth of connectivity. It was a beautiful board and at the back you can see the "crazy cool" copper plate designed to dissipate heat.
The performance of the board was second to none, in fact it was quite astonishing. I was able to reach 410Mhz on the Front Side Bus (FSB) which is a whopping 1640Mhz. At the time, there were very few socket 775 motherboards that were able to reach such phenomenal FSB. On top of that, the system was very stable at the 410Mhz FSB.
One negative aspect I'd like to point out is the inflexibility of the backplate. The initial idea of it was cool, but when I wanted to a high-end cooler, I was unable to remove the plate rendering rendering my aftermarket cooling solutions useless.
Gigabyte has reduced this board to around £220, so I still recommend it today if you're after a socket 775 motherboard. If you're going for a brand new system, I recommend checking out motherboards that support Intel i7 CPUs.
