The Core2duo line was released in 2006, making it even older than that graphics card. I hate to have to tell you but there really are NO modern games that you are going to be able to play decently with a Core2duo CPU and a ten year old graphics card. I'm sorry that your options are limited because of where you live and your financial situation, but it does not, and can not, change the fact that the only games you will be able to play even halfway properly are going to be whatever games were released near 2006-2009. You might be able to play a few titles that were common in 2010/2011, but you will likely have to do so with extremely low in game settings, and it's gonna suck.
Even back then, that was not a terrific card. Get a better graphics card, at least, or else live with the fact that you just can't afford to game. Sorry, but in THIS case, those are your alternatives.
