Reviews for the Rock Xtreme 840SLI

Rock notebooks are built to order, so delivery time is normally around a week. Here I am looking at what would definitely be a top of the range unit, very powerful and rather expensive, it is all but £3000 and today that is not cheap.

We did an initial field test with Rock's new Xtreme X840SLI-X9100 desktop replacement laptop, using an 18 year-old female online gamer and a 30 year-old male Xbox 360 addict. We opened the lid, turned on the power and within seconds got the identical awed response that went something along the lines of, “Whoa, that is soooo cool!” There's no question that Rock's new hardcore gaming laptop will be heaven sent for serious gamers who want the latest and best from Nvidia's graphics arsenal, yet flashy lights don't make for responsive controls, despite the welcome macro buttons. The price tag is high, but you'll get a reaction (and probably arm strain) wherever you take it.

With gaming laptops there's often a fine line between portability and power, but Rock's Xtreme 840SLI-X9100 falls firmly into the latter camp. This behemoth is most definitely a 'desktop replacement' in the truest sense of the term, as with a starting weight of six kilos (plus another 1.2kg for the power brick) it has the distinct honour of being the heaviest gaming laptop to have graced our labs - not counting the multimedia-oriented HP Pavilion HDX9095EA. It's big in every way, but despite its excellent Full HD screen, some innovative features and stonking performance in games, there are enough niggles to hold Rock's Xtreme 840SLI-X9100 back from coming recommended.

Comment
NVIDIA GeForce GTX 280M SLI:
Two GeForce GTX 280M graphics cards in SLI combination. The performance is about 0-40% faster than a single GTX 280M, depending on the application. Due to the SLI setup, users may experience micro stuttering, especially in the 30fps range.
These graphics cards are able to play the latest and most demanding games in high resolutions and full detail settings with enabled Anti-Aliasing.

Intel Core 2 Extreme: The fastest Core 2 Duo variants of Intel are called Core 2 Extreme. Technically, these processors are based on a Merom/Penryn (X9000) core like all other Core 2 Duo processors, too.
X9100:
The X9100 is the fastest dual-core of the Core 2 series and thanks to a free multiplicator can be overclocked easily. Later the expensive X9100 was substituted by the cheaper and more power saving T9900 (with a fixed multiplicator).

Laptops with 18 inch displays did not exist before 2008. The DTR-laptops can't be carried easily, need much energy but on the other side texts can be read easily and high resolutions are no problem. DTR mainly are intended for stationary usage on desks, where the weight and the energy need are unimportant.

6 kg: This laptop is heavy. Especially desktop replacements with 19 inch display fit in this class of weight. This class is too heavy, even for 17 inch DTR.
Rock: Rock is a British laptop manufacturer and focusses the UK market.
65%: Such a bad rating is rare. There exist hardly any notebooks, which are rated worse.
