Rock has made a reputation with its really extreme laptops. Xtreme SL Pro is no exception as it comes with two 7950GTX in SLI, an AMD Turion X2 TL-60 (2.0GHz), 1GB RAM (max 2GB) and 2 100GB SATA-disks (up to 2x160GB). A bit surprising its only 20″ display only has a resolution of 1600x1050px , which is a bit low if one wants to really use the power of 7950GTX SLI. Not as surprising there is no battery test, but apparently it’s possible to get a whole hour from the battery if you downclock the graphics cards quite a lot.
