Deviltech:

ATI Mobility Radeon HD 5870:

High-end DirectX 11 graphics card based on a desktop HD5770. Models with GDDR5 are ideal but there may be a bottleneck due to the 128 Bit memory bus.

Intel Core i7: The Intel Core i7 for laptops is based on the LG1156 Core i5/i7 CPU for desktops. The base clock speed of the CPUs is relatively low, but because of a huge Turbo mode, the cores can dynamically overclock to up to 3.2 GHz (920XM). Therefore, the CPU can be as fast as high clocked dual-core CPUs (using single threaded applications) but still offer the advantage of 4 cores. Because of the large TDP of 45 W / 55 W, the CPU is only intended for large laptops.  

720QM: The Core i7-720QM is the slowes Core i7 Quad Core in 2009 and clocks between 1.6 and 2.8 GHz (due to the Turbo Mode). Therefore, it combines the advantages of a slow quad core CPU with a fast single core one. Compared to the faster Core i7 mobile CPUs, the 720QM only features 6MB L3 Cache.

18.4: 18 inch display size is a rare and very big size for desktop-replacement laptops. 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.

5.5 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.

5.5 kg:

83%: This rating is to be considered as average, because the amount of notebooks with better ratings is about equal like the amount with worse ratings.
