Rating: 9.0.

If you have £600 burning a hole in your pocket then perhaps today's review product may interest you. The Gigabyte GTX980 Ti XTREME Gaming is a custom, heavily overclocked graphics card which features a semi passive three fan ‘Windforce' cooler. With a 12+2 Phase Power implementation and proprietary backplate, the XTREME has been clearly designed to push frame rates as high as possible.


The Gigabyte GTX980Ti XTREME Gaming Windforce is a hefty beast of a card – shipping with an all metal enclosure incorporating three large bladed fans – Gigabyte claim this cooler can cope with 700W of heat. Gigabyte have also adopted a LN2 mode switch on the PCB to unlock voltage and power limits – this is supplemented with an additional power connector.
