The first is the fastest regarding gaming . it can run any game at 1366x768 medium quality

Is there a lot of differences between GT 820m and GT 840m?

Huge difference :
Geforce 840M - 384CUDA cores
Geforce 820M - 96 CUDA cores

Geforce 840M is 50% clocked higher .

840M is 42-77% faster than 820M , it depends

The 1st laptop is by far the best for playing games. There is a pretty big performance difference between the 840m and 820m even though the 840m is only considered a mainstream GPU, not a performance GPU.
