ZOTAC now have 5 variations of NVIDIA's finest GPU giving you the choice of reference, overclocked, custom air-cooled, water cooled or a combination of the two so everyone, regardless of requirements is catered for. The AMP! Editions of ZOTAC graphics cards feature maximum possible overclocks yet still retain air cooling. The only options further up the hierarchy are Infinity Editions but for this you will need water-cooling. The AMP2! Edition GTX580's we have on test today feature a triple slot design giving the maximum possible performance from an air cooled solution.
