Under 5k what? Rupies? US Dollars? Clarification needed.
That said, as the person before me commented, your system seems very very old. You might want to consider a total system upgrade, starting from the CPU+Mobo and pairing them with a decent card.
You cant hope for a lot with this CPU, but if you want light gaming, sure you can get an RX 460 or even a 1050.
