Since you're in India, we can't really help you in picking out exact hardware since Newegg and TigerDirect doesn't ship there. Most members on this board are in North America so I'm not sure what options for purchasing hardware there is in India. However, there are some things you can do. That computer is not designed for games and will be quite slow. First, the CPU is a slow and is single core. Second, you have little RAM. Third, your graphics card is underpowered. According to Intel, you should be able to use a maximum of 4GB of DDR2-667 RAM. You can also use DDR2-400 with that motherboard too. It is possible to upgrade your graphics to something better. According to a currency calculator, 2000 INR is about $43 USD. Before you can upgrade your card, you need to know how many watts your power supply puts out, then go find a card that will run using that wattage. Your motherboard allows for PCI-E so your options aren't limited in terms choice.

The 504MB of RAM tells us that there is actually only 8MB being used for video (assuming 512MB total), although up to 128MB is supported. You need to load your BIOS and change this setting. It would also help to upgrade the RAM.
