I don't know how hardware prices in your area compare to the U.S. Your budget is at the bottom of what you can build a decent gaming machine for. You can read Tom's articles and see how they do it. You could take the hardware they used, and shop around for better deals with some of the less critical components such as the case and optical drive. http://www.tomshardware.com/reviews/value-gaming-pc,2578.html
