In terms of software Rock gives you a very clean Windows install - just the way most gamers will want it. Pre-installed you get BisonCam webcam software and the aforementioned CyberLink DVD Suite v6; Nero 8 Essentials on an included disc rounds out the package.
At this stage it's also worth mentioning the included laptop bag. It's as basic as it gets, but a nice addition for those who don't already own one. It has a padded carrying handle, shoulder pad and inner section, providing some protection for your expensive new gaming notebook while on the move and also storing the system discs and power adapter - itself a large brick weighing over half a kilo.
Coming in at 3.3kg (not including the AC-adapter), the X620 is hardly a lightweight, but still relatively portable for a machine this powerful. Despite using an identically-rated six-cell 4,400mAh battery to Novatech's X50MV 15.4in Pro Gaming Notebook and using a more power-hungry graphics card, the X620 put in a slightly better performance, with two hours and 15 minutes of use in the non-intensive Reader test.
This dropped to an hour and 36 minutes in the DVD test with the screen at 100 per cent brightness. This is enough for moving around the house but doesn't give you much flexibility, a fact compounded by the lack an extended battery option.
Even so, overall the Rock Xtreme 620 represents good value for money. To put this into context, a similarly-configured Alienware Area 51 m15x (except with a lower-resolution screen and slower 2.6GHz processor) would end up costing £1,986 compared to the £1,762 that lets you take the Rock home. Since games are throttled by the GPU rather than CPU, an even better option would be to go for the Intel 2.53GHz T9400 configuration which, everything else remaining the same, would set you back £1,585. It's also worth remembering Rock's very generous standard three year warranty, something that would cost a lot extra from many manufacturers.
Rock's 15.4in gaming notebook outdoes its 17in predecessor in every way and gives other similarly-sized gaming machines a run for their money. It's well-built and looks the part too, while striking a nice balance between performance and value. Our only real complaint is that it gets somewhat noisy while gaming, but this will probably be drowned out by gunfire and explosions from the impressive speakers.
