For that money you'll want a 5770. It's £130 in Britain, but that's with our stupid prices, I don't know what it'll be like in India. This ATI card "shits all over" the 9800GT being recommended here, it might be more expensive, but it's not a big deal. If you can get a 5850 (I paid £199, it seems to have gone up to £240...) in your budget then that's where you should go. This is the card I have, it's better than the GTX260 I used to use.

The 5000 series seeing as it is a new architecture is going to be around for a while. You're welcome to wait for nVidia's Fermi to come out, but if it's anything like the GTX200 series release then the cards will be rather expensive (at least, out of your budget).
