Shouldn't you be upgrading the motherboard first? I don't think your motherboard can support that card. Then again I might be wrong. But you should start by upgrading your mobo first.
why wouldnt the board support the card. The intel dh61ho MB has a pci-E 3.0x16 slot on it. Not knowing what you have available in India, I would go with ether EVGA, Gigabyte, Zotac, MSI, Asus. You also have options between stock cards and factory overclocked cards within those brands as well.
