Hmm. I don't think MSI or Sapphire ATI cards are available in Kolkata at least no 4770. Check with these shops:

A month ago when I bought by rig, there was no 4770 available. Two weeks ago I called Starcomp and they quoted 7500/- + VAT for XFX 4770 and they had 10pcs ready.
Arihant called me and quoted 7400/- + VAT for XFX4770 on the same day. As palit has stopped to produce ATI cards, you can't get it from Tirupati. But they are also distributor of MSI, so verify with them. Call Mr. Abhishek Kejriwal (Manager) @ 9339207519 if the person at shop doesn't help you or tells you that it is not available.
