the laptop will have 6970m's in crossfire which is a cut down Mobile version of the GPU.
1536 Stream Processing Units
880 clock speed
5500 Memory clock speed:
960 Stream Processing Units
580 - 680 MHz clock speed
4800 Memory clock speed
the CPU should be about on par with the desktop version but u obviously see the size of a normal 6970, do you really thing they can fit 2 of those full cards with propper cooling into a laptop. let alone leave room for the HDD, motherboard, RAM and ROM drive? No they have to cut down the power and there for the heat generation to fit them in.
btw there is almost 0 performance between the i5 (2500k) and i7 (2600k) for gaming performance.
