I have read the specifications of all these laptops and i'm confused which one to buy, here is the difference i figured out. I'll mention the company name as model number is mentiond in the question.
Dell is giving:-
4GB RAM, 3rd Gen i5 processr and 2GB DDR5 NVIDIA GT 650M graphics with 17inch screen!
priced around Rs.64000/-
Samsung is giving me same spec nd much more:-
8GB RAM, 3rd Gen i7 Procsrr nd 2 Gb NVIDIA GT 650M but it's DDR3 not DDR5, with 15.6 inh screen
around Rs.59000/-
Lenovo gives:-
8GB RAM, 3rd gen i7 porcssr nd 2GB NVIDIA GT 650M DDR5 SLI graphic nd 15.6 inch screen
around Rs64000/-
all three laptops have 1TB hard disk.
Now please tell me what should i buy, more high configuration in lower prices (Samsung)? or go with Lenovo? or go with brand name => Dell ! with 17 inch display but with only 4 Gb RAM -_-
budget is around 65000/-
