4) HP Pavilion 15-E039TX Laptop (3rd Gen Ci5 3230M/ 4GB/ 1TB/ Win8/ 2GB Graph) - Rs 46690 www.flipkart.com/hp-pavilion-15-e039tx-laptop-3rd-gen-ci5-4gb-1tb-win8-2gb-graph/p/itmdn4d9wykhdcpz?pid=COMDN4CZGFMGJNTN&ref=1d2b85fc-a03d-4c7d-844b-ec9e8dc95a81

Now I am confused between:

1. Which Processor and chipset is best?
2. How much graphic card is enough? (Not a gamer)
3. Is any of this laptop future proof i.e. it should at least support upcoming latest programming softwares which eats more processor and memory.

Laptop will be mainly used for multiprocessing.It should be at least capable for following:

1. Visual Studio 2012 and the upcoming versions for at least 4 years
2. SQL server 2008 R2 and above
3. Sharepoint
4. Blend
5. Photoshop

Kindly suggest. If anyone know any good laptop with good configuration in the 50k budget kindly suggest.

Thanks in advance.
