i7 3537U has Intel HD Graphics 4000 , so GT 740 will contribute to higher 3D performance - 5.2x faster but what does it mean.in frames per second !?

. My concern is whether 740M is well cooled . I like gamers laptop with additional cooling for the gpu - other holes .But they are too expensive when made by decent manufacturer
