Gamers are funny people, they always want the top of the range of everything and naturally be gamers their competitive nature means that they must have the best computers around with all of the trimmings, even if they are not required and will probably never be used, but they are there just in case.
The Sager NP8690 is probably one of the best or rather most powerful gaming laptops around in the 15.6 inch category, and as gamers like to be fussy over their specs, they get to choose the processor from the Intel Core i7-720QM, i7-820QM or i7-920XM.
