Hi, not really related to your query, but if you are buying the system only for gaming then I would suggest get an i5 and use the savings to get a decent graphics card. Nothing beats the disappointment when your shiny new desktop can't play the latest games with butter smooth framerates.
Thanks jc36lect3r, if i were buying new i would have gone that way but im getting the processor from a friend, details under...
btw is your name 'jceblecter' been out of touch with 1337 5p34k for quite some time ;P
guptavis you did not tell me you were building a gaming RIG, anyways I have the same suggestion as jc36lect3r and here is a RIG I can suggest --
Intel Core i5 3450 ~12500/-
GIGABYTE-B75M-D3H ~4500/-
Corsair Vengeance OR G.Skill RIPJAWS 4GB x2 1600MHz RAM ~3600/-
AMD HD7850 2GB / 7870 2GB ~16500/- OR 22500/-
Seasonic S12II 520W [but I think you already bought the S12II 430W so you are limited to the HD7850]
If i was looking to buy a new rig i would come straight to you but this just happened through a series of complex events. Read below.
@all: Thanks for all the suggestions guys, am looking forward to go all guns blazing into atleast some of these. Might not get too much time, i do have a job, IAS mains paper and other family responsibilities to take care of... miss the good old college days of 8-10 hours gaming... hhhhmmmm....
Also, its not a rule but i generally like games that are mystical, mythical etc.. i mean to say spells, amulets, god powers over guns, tanks, planes etc.
Also i know of the general places but if someone can PM me a 'place' where to get these. a 'place' specialising in game releases maybe? A few that i knew of are now defunct.
For those who are interested, here is the story behind this Mad brew of hardware.
As stated in my first post, i used to be a gaming freak during college. (it may or may not be a reason of my getting a second division degree)
after that due to various reasons couldnt game for lack of good hardware. had only a feeble AMD sempron system and had basically thought my gaming days had up.
But a few months ago i paid a visit to a friend's place. He is a rich guy but not much knowledgeable about computers (i confess i dodnt know much either). He is the kind who brags ' i have an i7 & 2TB hard disk' and would have no idea of what is a RAM or motherboard!

He was bragging that he got a 'Rs 12000 ka graphic card'. He said he'll show me what it can do and booted the computer, 5 minutes later my jaw really dropped to the ground! He ran Diablo3 and a few other games in high definition and i could not believe my eyes. The old days came back to me and i asked him more about his graphic card. It came as no surprise to me that all he knew was 'its imported Rs12000 ka graphic card'.
I opened his computer and had a look at it. It read ' Asus HD7770'. I made up my mind that i was getting the same immediately.
I came home and searched all over. found the cheapest HD7770 for ~Rs 9700. Ordered it.
But when it came i realised that it needed a power connector which was not there on my PSU. Then i read a little and thought i should get a new PSU. But then i read more and realised that my whole system would be a MAJOR bottleneck and the card wouldnt be able to do much. So i was going to have to buy a whole new computer which involved a lot of finances which were already drained after the 10k spent on the HD7770. So saved up and read up on every thread here. Am an AMD 'fanboy' but reading the plethora of reviews and bechmarks decided on going the sandy or ivy bridge way.
But still could not hope to gather the insane amount required to get the proc+mobo+PSU+more RAM.
A few days ago the same friend said that he wanted to upgrade to '3rd gen i7'. I made a deal with him to buy his old i7 processor (about 8 month old) for ~10-12k (which turned out to be the i7-2600).
So i am gonna get that processor when he gets his 3rd gen i7 in a couple of days. pairing it with GA-B75M-D3H and 4 or 8gb ram and already ordered and recieved S12II 430W. This has broken the bank though. finding it difficult to fund the processor and mobo, so may sell the 7770 if i can and get a second hand cheap card for now and upgrade later.
