The MSI Lightning series has long been one of the better manufacturer special edition graphics cards. Starting on Nvidia based architecture MSI have now brought the combination of the Twin Frozr cooler and pre-overclocked GPU across to the already great Radeon 5870.We recently looked at the MSI Hawk, which was the 5770 version of this combination and today we're going to be looking at the MSI HD5870 Lightning.Is it everything we hope for?
