$800 will buy a decent PC. Unfortunately, few on BC are familiar with Indian computer stores. However, we can suggest laptop models but know that not all models are available in every territory.
Here are some configuration suggestions. You cannot purchase from Newegg since you are in India, however it can help you see what is available.Acer Aspire AS6930-6942 NoteBook Intel Core 2 Duo T6400
- It has plenty of RAM, a decent CPU, and a large screen for within your budget.SONY VAIO NS Series VGN-NS255J/L

At least a dual core processor, try to stay away from Turion and Centrino processors as they are often underpowered. The CPU should have a speed, for a laptop, of at least 2GHz. As for RAM, 2GB is suggested, but if you can afford to purchase more, go for it. If you are into video games, a laptop is not an ideal solution given the low-powered options in video cards. If you are a general user who isn't going to be gaming, you don't have to worry too much about the video card.
