GT 650M vs GTX660M

[fgin23]

Which laptop graphics card is better for gaming, when both of them are on a 1920x1080 screen.
How about a 1366x768 screen?
How does the GT 640M compare?

Thank you

GT 650M is around 25% faster than GT 640M.

The GTX 660m is too weak to play games at 1920x1080 with the highest graphic quality settings. Probably good enough with medium quality, but it depends on the games. For 1366x768 resolution it is very powerful, then again it's only a 1366x768 resolution screen.
