Cheap Graphic Card for Rs. 3500 budget for casual gaming

Hi Please suggest me a graphic card for my system . I am looking for cheap card with price Range of Rs. 3K-3.5k . My needs are moderate, only need to play casual gaming and don't want to play games at high settings but games mst be playable. All latest games should play but playable. My system is core2duo , 3G RAM , 500GB hard disk drive.

In this budget you can get only little older graphic card. I suggest you to give a look to following :

From AMD --> 4670 or 5450... former is DD2 and later is DDR3 .
From Nvidia you can get GT220 and GT9500
