NVIDIA Quadro FX 880M: Professional middle class workstation graphics card that is based on the GeForce 330M core but features lower clock rates.
Non demanding games should be playable with these graphics cards.

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.
620M:
The Core i7-620M is the fastest Dual-Core CPU for laptops (at the time of introduction in Q1 2010). The 620M clocks betwenn 2.66 and 3.33 GHz due to the Turbo Mode and because of Hyperthreading, 4 threads are executed simultaneously. In the package, Intel also included a second die with an integrated GPU (GMA HD) and a memory controller. Therefore, the TDP of 35 Watt of the whole package is still quite good.
