^Dude get the 5770 instead of the 4890. Although the performance would be a notch lower for the 5770 (an overclocked 5770 should equal or beat a 4870 btw), the TDP is much lesser and has DX11 support so should help you in the long run assuming you may not do another upgrade anytime soon.
You can as well make do with a cheaper enclosure instead of the HAF922. See if you can find a CM590 or a Lancool PC-K56. Since you are from Mumbai, call up Phoenix and pick one up from his place - Linky!
Invest in at least 4gigs of RAM. You can utilise the money saved in the above 2 purchases for the additional pair of sticks. And do consider the Gigabyte variants over MSI or Asus.
