Mobile gaming rigs don't tend to be particularly upgradeable, so it's important to get all the horsepower you can up front. With that in mind, MSI's latest is delivering a little more oomph than its last lap-warmer. It's the GX680 and it's rocking an Intel Core i7 2630QM processor paired with GeForce GT 555M graphics, NVIDIA's latest bid at laptop pixel-pushing supremacy. That card has 1GB of GDDR5 memory onboard, while the system itself can be configured with up to 16GB of DDR3 -- rather a lot for a laptop. A 15.6-inch, 1080p display is available, along with dual 750GB HDDs, which can be configured in RAID 0 if you like living dangerously. Blu-ray is also on offer, along with a THX certified Dynaudio sound system that is said to deliver audio "heretofore found only in cinemas." No price yet, but as always with MSI that kind of hyperbole comes for free.
