[AHMED_92]

Hey Guys,I'm going to the college next month and looking forward to buy a laptop.I'm an engineering

student and am going to use graphic intensive apps like CAD so I need a good graphic card and a good

processor like core i7(3rd gen more preferable).Minimum hard disk space of 500gb and min RAM 8 gb and a

good battery life.


I have chosen Hp Envy 15-3247nr and Dv6-7023Tx please tell me which one to choose also if there is some

thing better than these two
