Double graphics, what's the good?

Core series, and did not adopt integrated graphics and CPU integration technology, only y460 support dual graphics card switching. For 450, I do not recommend, because 460 everything is better than 450, is 450 of the comprehensive upgrade version. As for y460 's graphics card, let's first say that the CPU comes with integrated graphics, this CPU because it is integrated, almost no amount of heat, and its performance to meet the 3D games in addition to almost all the day-to-day needs, power consumption is very frugal, is the use of battery mobile office of choice, for this benign integration of Intel, I very much agree with it. So what about y460 's independent graphics 5650? The summary of a sentence is impeccable. Not to mention that a 5650 video card is very good, even if the desktop can use the graphics card is also very good. 5650 of the graphics card is y460 the strongest one configuration, Win7 score of 6.7, even if the Y460i5 430m CPU score is only 6.4 so, the landlord should know how strong this video card! Of course, because of its outstanding performance, the power dissipation is also unavoidable, The standby time is significantly reduced when using the battery and his powerful heating power is greater than the thermal power, in the case of not using the cooling base does not open air-conditioning, the hot weather to play a large 3D game, even if the machine can run, heat dissipation also can't keep up, this is why the Internet on the y460 of the strong temperature point of the people, especially the reason Of course, with the radiator base, it is better to open an air conditioner, the situation will be greatly improved.
