Gigabyte GeForce GTX 780 Windforce 3X OC

Meet the Gigabyte GeForce GTX 780 Windforce 3X OC

NVIDIA's latest flagship graphics card, the GK110-based GeForce GTX 780, impressed us in our reference card review, with performance very close to, and even exceeding, NVIDIA's GTX Titan on some benchmarks. How will a factory-overclocked, custom card fare? Let's find out.

 

Gigabyte's GeForce GTX 780 Windforce 3X OC is overclocked 91MHz at the core, raising core clock speeds from 863MHz to an impressive 954MHz, although memory remains clocked at the default 6008MHz DDR. Like the reference card, it features a 3GB frame buffer.

As its Windforce 3X name would suggest, the card sports a custom triple fan cooler comprising of three 80mm fans mounted onto a skeletonized fanshroud, and a full aluminum fin-stack that covers the voltage regulator and memory area, all connected to two 8mm and four 6mm thick heat pipes.  

The dual-slot cooler isn't much larger than the reference design, measuring 292 x 129 x 43mm. Like the reference design, it requires one 8-pin and one 6-pin Molex power connector. 

 

 

The Gigabyte GTX 780 comes with Gigabyte's OC Guru II software, which supports control for NVIDIA's GPU Boost 2.0 technology and also provides an easy way to tweak and monitor core clock, memory clock, fan speed, gpu voltage and memory voltage. Locally, the card comes with a 3-year warranty period and it has an SRP of just S$999. It will be quite interesting to see how this windy card performs.

But before we begin drilling down, here's how the Gigabyte GeForce GTX 780 Windforce 3X OC compares against its competition:
