Most AIBs now have their own custom OC and monitoring utilty, and Gigabyte's take is OC Guru. Other than adjusting core and memory frequencies as well as fan speed, you can save your settings in five different profile slots and load them for use later. Gigabyte should consider adding a GPU stability tester (like MSI and their Kombustor) since it's the most logical thing you would want to run after changing the clocks.

The twin direct touch heatpipe and large heatsink array certainly helps conduct the heat away from the core, which doesn't really need much cooling anyway since its only outputs around 110W (puny compared to the power hungry enthusiast cards). In fact, we reckon the card could make do with a smaller heatsink and only one fan like on the reference design, and still operate within safe temperatures.

As with any form of overclocking, your mileage may vary. Our test sample seems to like being pushed harder than the ones we see on the other review sites on the web. We managed to obtain impressive overclocks on both the core and the memory. These values were stable during the benchmarking process and no artifacts or lock-ups were encountered.

  Reference GTX 650 Ti Gigabyte GTX 650 Ti Windforce Gigabyte GTX 650 Ti Windforce with OC (1.175v)

This is the effect of overclocking in Battlefield 3, which clearly improves the overall user experience and consequently the gamer's kill death ratio.
