i5 4690k is great for gaming and definatly enough for your needs, I wouldnt suggest getting the i7 processers unless you are doing video editing/rendering and other intensive tasks.
But I think you should go with the GA-B85M-D3H (better build quality; more ram slots, two PCIE 16x and better cooling system)
If you want to have PCIEx1 this would probably be your best option: http://mdcomputers.in/products/motherboard/intel-platform?product_id=3357
another build can be their if you want much lesser than 44000 rupees
