^^ Core i3 2100 ~ 6200/-
ASUS P8Z68-M PRO ~ 10000/- [I'm not sure of this price, try to find out]
Corsair XMS3
OR G.Skill RIPJAWS 4GB x 1 ~ 1650/-
AMD HD 6950 2GB ~ 16900/- [if your budget does not allow OR you want to purchase a HD 7*** series card get this card instead -- AMD HD 6670 ~ 5400/-]
Seasonic S12D 620W ~ 4600/-
NZXT Gamma ~ 2300/-
SSD will go out of your budget, but if you want one get a Corsair Force3 120GB drive ~ 12000/- [As Corsair has a good A.S.S. network in India compared to OCZ]
An AMD set-up means you'll forfeit the Intel set-up which can be upgraded to the Ivy-Bridge processor as well as the Phenom IIx4 line-up is now EoL, performance is not as good as the current Core i3 line --
AnandTech - Bench - CPU.
Hope this helps.
