1. Gaming

   
   




2. Browsing

   
   




3. cad Designing(mechanical field)

   
   




4. For reading.

   
   

My first confusion either I should buy in india or abroad which is best.

My detailed required config is:

15.4" Screen size.

Intel core 2 duo processor 2.0 to 2.1 ghz.

2 gb ram.

Dvd writer.

wifi and bluetooth.

160gb hard disc.

built in camera & mic.

after reading some reviews I feel g force is good option for all 3d game lovers

but I feel integrated graphics card is cheap and satisfy my gaming requirement

I need good service.

immediate response from the company.

I have worked in laptops more than a year.

I should also want to get satisfied with the rate of the product.

So I finally come to an conclusion of buying laptops either from dell or hp.

SO which one shall I chose.

And once again where shall I buy this either in india or abroad.

Please give me a good solution as soon as possible.

Thanks and Regards,
