look for a lenovo with a quadro, thats what we use in our engineering dept. For 60,000 Rs you might be pushing it a little but you should be able to find something similar. Try to find something like this: http://www.newegg.com/Product/Product.aspx?Item=N82E16834146732
Not quite what we use but definitely in the same family. Obviously depending on where your at you may have to use a different site, but our lenovos work well it surfcam, mastercam and autocad.
One really important question you need to ask yourself is do you truly need a laptop? Some of my associates use them but I opted for a desktop for the same price and my rig annihilates there laptops. Just some food for thought.
