I'm looking to buy a new laptop that I can use to play games like battlefield 4 & ghosts (all on low settings). The laptop I've found that's within my price range (less than $850), has an i5 3230m and a NVIDIA GeForce GT 740M 2GB. The gpu is good enough for what I need, but I'm not sure if the CPU will be powerful enough to play any of the newer games coming out. Will it last or should I pay an extra $150 for a i7 3632qm?
