Nvidia's GTX780 Ti has been a big seller in 2014, leading the high end performance market. We have reviewed many GTX780 Ti's since the official Nvidia release last November, but due to reader demand today we look at one of the fastest overclocked models from Gigabyte. Their Windforce OC model is clocked at a whopping 1,020mhz out of the box. How does it handle at Ultra HD 4K resolutions?

Gigabyte have fitted a special version of their triple fan Windforce cooler to the GTX780 Ti. Gigabyte name this particular cooler the WindForce 3x as it incorporates a unique ‘Triangle Cool' methodology. The company are using three quiet PWM controlled fans, a huge ram heatsink, two 8mm heatpipes and four 6mm heatpipes.

The Gigabyte GTX780 Ti Windforce OC is clocked much higher than the reference GTX780 Ti. The GK 110 core speed has been increased from 876mhz to 1,020mhz. This is the highest clocked GTX780 Ti that has entered our labs. The GDDR5 memory is running at 1,750mhz (7Gbps effective).

Today we test hardware with a 30 inch Apple Cinema HD display (2,560×1,600) and with the ASUS PQ321QE Ultra HD 4K Monitor (3,840×2,160).

The 4K ASUS PQ321QE panel retailed last year at a whopping £2999.99 asking price, but as we predicted this has dropped in 2014 to £2,279.99 inc vat. We expect further price cuts in the coming months.

Today we test using the latest 335.23 Forceware drivers.
