I've shortlisted three laptops. All three have the Nvidia GT 740M. One of them has Intel i5 4200M, one has i5 4200U and the third has i5 3337U processor.
I checked and the 4200M is better than the 4200U which is better than the 3337U. But how much difference of frame rate will they give while playing latest games?
