The Updated model of our long term test subject, Rock·s latest Xtreme 770 has it all. A Penryn-based Core 2 X9000 processor, which is unlocked for overclocking, and an incredibly fast NVIDIA 8800M GTX graphics card. While it doesn·t have the illumination and bonus features of the XPS range, it is much lighter. A gaming laptop that can also be described as portable? That makes a change.
