Advise required for purchase of Laptop

Dear Friends,

I wish to buy a laptop of HP. I can invest around 50 K to 56 K.
While searching the web I found three latest models

1. HP Envy 4 -1046 TX
2. HP Envy 4 -1025 TX
3. HP Envy 4 -1002 TX

Please suggest which one should I go for.
Also suggest the difference between these laptops.

Thanks
Nikhil Gupta
