The GTX580 has been Nvidia's finest moment. The card has been a big seller since it was released and it leads many of the performance charts when we factor out the dual GPU solutions. Today we are looking at the MSI N580GTX Lightning, a heavily modified card designed to target the enthusiast gamer audience.
When MSI create a custom card, they don't do things by half measures, this card not only receives a custom PCB implementation from the MSI team, but it is supplied in a highly overclocked state with a metal, two fan cooler (Twin Frozr III).
MSI have also created a proprietary PCB design which allows for various software based voltage adjustments, just in case the preoverclocked settings aren't enough.
