Got some spare cash to upgrade that weak old graphics card? If you have £500 burning a hole in your bank account then the Nvidia GTX980 is the first choice on our list. KitGuru has already looked at custom partner cards from MSI, ASUS and Palit but today we look at something very special indeed. The Inno3D GTX980 iChill Herculez X4 Air Boss Ultra is without a doubt one of the most hardcore graphics cards to grace our labs ? featuring a scary looking four fan heatsink, and crazy ?out of the box? clock speeds. This is not one for the faint of heart.
