Wish I know enough about Indian markets to help. If this all works in your budget this looks like a good build, but definitely go for the 3500 at those prices. This is a very shoestring budget for a new computer if the currency conversion is accurate. This computer would be able to play games on low at 1080p, but the experience might be choppy. I would recommend getting a better GPU but the prices are so high right now that I would honestly just stick with this then wait maybe a year or two until prices settle down again and upgrade to something like a 1060 or a 1660. Remember when you're building cheap builds not to shy away from used parts, except for the PSU and the storage. Never buy a used power supply, HDD, or SSD. You might be able to get a used 1060 for just a little bit more than you're getting that 560 for if you try Ebay auctions.
