^^ The link you posted above is not correct as it pointing to some where else with some core i7 and core i5 mobos
BTW, is this your mobo :

According to the specs ( found on some other sites ) your mobo has 1 PCI Express x16 slot - so you will be able to use HD4870 but your cpu may bottleneck the gfx card ( what cpu do you have - mention the model name - use cpu-z to get the info ) and you will need a powerful smps like corsair VX450W @ Rs. 4K for HD4870. So I would recommmend you to go with HD4670 or a 9600GT instead ( provided you had some good psu )
