    I need new notebook for following use :
    Making college presentations , writing thesis etc.
    Watching Movies
    Listening to Music
    Internet Surfing.
    Downloading movies / music etc.


    Now I am getting 2-3 laptops at very good price and need others thought on what would be the best deal , i know its very subjective but your thoughts are super welcome !!!

    In the following one I am getting 2nd gen i7 but am loosing out on 1600*900 resolution screen :
    Samsung NP300V5A-S0CIN Laptop (2nd Gen Ci7/ 6GB/ 1TB/ Win7 HP/ 1GB Graph): Flipkart.com: Compare, Review Samsung Notebook

    In this I am getting 1600*900 screen but only 3rd gen i5
    Samsung NP550P5C-S01IN Laptop (3rd Gen Ci5/ 6GB/ 1TB/ Win7 HP/ 2GB Graph): Flipkart.com: Compare, Review Samsung Notebook

    In this I am getting 3rd gen i7 but am loosing out on windows and screen resolution :
    Asus K55VM-SX086D Laptop (3rd Gen Ci7/ 8GB/ 1TB/ DOS/ 2GB Graph): Flipkart.com: Compare, Review Asus Notebook

    Then there is a acer laptop in which i am getting 3rd gen i5, 1gb niveda 630 , 4gb ram , 750gb hdd and backlit kit ...this laptop is 7k cheaper than above models


    If I had to choose what should be better 3rd gen i5 with 1600*900 resolution or 2nd gen i7 and very reasonable price or 3rd gen i5 with back-lit keyboard or 3rd gen i7 but no windows.

    I am getting swayed towards laptop with backlit keyboard.

    How good 1600*900 resolution is over standard 720p , is it huge difference or negligible difference .

    If I had to choose between 1600 resolution and i7 what should it be.


    I need to listen to some opinions on what configuration to choose .

    FYI : I don't play games as such dosent matter if these laptops have good graphics or not ..

    the higher resolution the better ofcourse and screen upgrades are worth it. A 2nd gen i7 is much better than a 3rd i5 asuming we are talking about a quad are i7 and the i5 3210m.

    The Sandy bridge i7 will beat any i5 for the next five years easily; unless the processing speed of the i5 exceeds over 5.6Ghz per core.

    For what you plan to use the notebook for, I would go with the 1600*900 screen + 3rd gen i5.

    You will be more productive with a high res screen. The notebook should also run cooler with that CPU vs a quad core.

    The i5 is quad core...it just doesn't run any threads like the i3 and i7.

    I'd not be so sure about the 5.6GHz. That i7 has a maxiumum clock of 3.1GHz but that is for running on 1 core. With all 4 cores it is more likely to run on 2.8Ghz-2.9. So if you multiply that with 2 you get the 5.6Ghz. But the i5 has got multithreading which could increase maxiumum preformance by 20-30%. So more realisticly would be an i5 with 4.5GHz to match the quad core i7. I'd not say that i7 is twice as good but it is lots and lots better.

    4 threads doesn't equal 4 cores:
    ARK | Intel® Core

    The i5 only has 2 cores, but it has 4 threads.

    99% of the time...i3 has two cores and two hyperthreads. i5 has four cores. i7 has four cores plus four hyerthreads.
