Summary: I got this processor in my Alienware 18 laptop back in October 2013. It has had no trouble running any application I throw at it including performance demanding games. I have two 4GB GTX 780M graphics cards running in SLI with this i7-4900MQ & the processor never bottlenecks the graphics cards. In fact most of the time the 780M SLI bottlenecks the i7-4900MQ. The only thing bad about this CPU is the price. This is an expensive upgrade for a laptop.
