You should just get the MB + 5800k + 8 GB memory + PSU now. It should run most new games adequately at medium settings if you OC the memory and CPU. Then buy a worthwhile video card later when you have the cash. If you try to fit everything into a small budget, it will come out like a budget computer. The other option is have a lot of patience and wait for sales. I don't know about India but I can find deals here(US) all the time. Like my Corsair CX430 was $30 - $10 rebate. Have patience and you can have a good gaming computer with that budget.
