I built this for you, it's a bit overbudget, right now it comes in at 77925.78 INR. If you want a gaming rig, an i5 would give very close performance to an i7 and be about 6248 INR cheaper. Also, if you didn't need a copy of Windows you could also save another 6248 INR.
By the way, do you need a keyboard, mouse, and monitor in this build?
