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.
Modern games should be playable with these graphics cards at low settings and resolutions. Casual gamers may be happy with these cards.

520M:
The Core i5-520M has only 3 MB L3 Cache (compared to the I7-640M) and clocks between 2.4-2.93 GHz (Turbo Mode). Thanks to Hyperthreading, 4 threads can be processed simultaneously. An integrated graphics card (GMA HD 3150) and a DDR3 memory controller are also included in the package.
