I am looking to upgrade my graphics card and I dont know which one to get should I get this http://www.newegg.com/Product/Product.aspx?Item=N82E16814121319 or this http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=4128445&Sku=P450-9616 if I got the first one I would probably get 2 unless I dont need it. I have a 19 inch monitor.
