secondly what graphic card can i buy for it budget 7500 INR ie 140 USD
i prefer mainly amd radeon cards but suggest nvidia card too
its not a bad mobo at all. It's a B75 so will take any new Ivy Bridge CPU up to I7-3770k which is a monster CPU.
What graphics card to go with it depends on you. But for that price maybe a 7750, no aditional power requirements for PSU, which will save you money, and will game decently at 1680 x 1050 res (this is just as a guide). Alternatively for more money, but better performance a 650ti Boost would be a great card, for a good gaming experience.
