gt650m

I am confused about two graphic card i.e. gt650m and amd 7730. Please help out with their gaming performance.

Hi, I wanna buy a laptop with i7/FHD/650M(GDDR5) . Are there any options as of yet in India .? Also Does any one know when HP will update their dv6 with GT650M .?:-o

How would you rate the gt650m for high end gaming? And, is it in any way inferior to the old gtx 260m? Am asking this because i'm getting a replacement m14x for my m15x. Other specs are way better in the m14x. Just want to know about the graphics. Comparasion between these two might seem silly...
