That board supports AGP 8x/4x. AGP cards are few today but the best one I would buy for an old socket A system would be HD4650 http://www.newegg.com/Product/Product.aspx?Item=N82E16814102851 But I would only buy it if the card I had in there failed. More powerful cards are HD4670 and HD3850 but both would be held back by your single core CPU even if it is 3200+
