You need to make sure to get a Xeon E3 1245
V3 , the V2 and V1 will not work with your motherboard. Other than that, that CPU will work no problem, indeed there will only be a slight difference in performance.
Why can't you find the 1231 in India? Here it is:

It's Rs. 3000 cheaper too.
Will do. It's V3.
I already contacted the seller you are referring to about a month back. They said the order is against payment only, i.e. I will have to pay first, then they will import it, and only if that goes smooth then they will ship to me. Hence I will have to say goodbye to my cash and wait for months. Because Indian customs and duties are terribly rigorous and painful. So unless the product itself is not in India, there's actually 50-50% chance you will even get your item.
Plus I do not like that particular seller as I know people who got damaged/used product from them.
I really appreciate your effort to look up Indian sellers for 1231/1246 V3, but frankly there's none ATM.
For instance, in Amazon IN the 1220V3 is 25,000INR, 1230V3 is 31,000INR and 1245V3 is 34,000INR. I wrote to Amazon IN requesting them to sell 1231 and 1246. Their great CC said definitely. Took them 1 month which is okay, but they bought only 2 of each priced at 25,000 and 29,000INR respectively which went out of stock as soon as I reached home. Now I have both the 1231 and 1246 in Amazon cart under 'saved for later' due to unavailability. You see the sheer absurd price of every one of them, don't you. But I am not one of those guys who cries for each buck so I was willing to shell out the extra 5-10 grand.
Besides Amazon, India has Flipkart that you can trust, which has recently listed the 1245 V3 for 21,000INR. Of course I will end up spending $40 more but that's okay. One less $40 game in my Steam library.
There are many sellers like the one you referred, and all of them want the money first and only then they will order. They say things like "Sir, it's against order only" or "Pre order only". I ask them to take a small amount as security and I will pay as the item will enter India but they won't bend.
I have been ordering stuff from overseas all my life. Only once Amazon International delivered under one month as the item was not electronic. Otherwise I still have stuffs to be delivered 8 months pending.
I didn't mean to bore you, I just want you to know how the Indian system works. And also how unlucky I am.
