Hey Vijay. I've seen some of your other threads, but I did not respond because I wasn't sure whether or not you were trolling (no offense). It seems that you came to these forums for some help with getting a new computer with these requirements:
My purpose is Internet ,HD Moovies,Music and mid level gaming.
i m not a kind of game freak..but want to paly atleast NFS Shift,GTA 4 ,Far Cry...
It sounded like you were looking at laptops at first, but you got discouraged by the performance you'd probably be able to get from the models you were asking about. While there are some portables that would meet your demands and budget (the G73Jh and maybe a couple others), availability and warranty considerations kind of knock those out unless you can find a good place to get one from a business located domestically.
When you asked about desktops, the enthusiast crowd here immediately tried to talk you into custom building without knowing about your computer knowledge level (apparently not that high (not trying to be offensive at all, again)). I would suggest that you just go with a Dell similar to one you listed in one of the other threads, rather than spending countless hours reading and asking questions in many threads across the various boards. I picked this one off of
http://www.dell.co.in/.
Studio XPS 8100
PROCESSOR Intel® Core i5-750 Processor (2.66GHz, 1333MHz FSB, 8MB Cache)
OPERATING SYSTEM Genuine Windows® 7 Home Premium 64bit Edition (English)

~$1,410 or Rs.66,424 before tax and shipping if either of those apply there. Maybe you can get a better deal since you said your cousin works for Dell in another thread.
That system gets you a bit more power than any notebook in that price range (maybe a $3k clevo could catch it). It will definitely meet all your requirements. For those applications, the i5 750 CPU is equally powerful to the i7 860, so don't be concerned about that. You also have the ability to easily upgrade the GPU in a year (has to be about equal power draw, but with better efficiency then, it would still be a good upgrade).
If you have more concerns, or if I have made wrong assumptions and you have other preferences which require revision of my recommendation, please post them here, or in one new thread in general hardware so we can get things sorted out for you once and for all. Good luck with whatever you choose though!
