im wondering if i will be able to get the most out of the graphics card (http://www.newegg.com/Product/Product.aspx?Item=N82E16814102878) if i have an intel core 2 duo e7300(http://www.newegg.com/Product/Product.aspx?Item=N82E16819115132&cm_re=e7300-_-19-115-132-_-Product) or should i upgrade my cpu first?
