Hi, i currently have a gtx 780 acx sc, http://www.newegg.com/Product/Product.aspx?Item=N82E16814130918, and a asus 144hz moniter, http://www.newegg.com/Product/Product.aspx?Item=N82E16824236313, what im planing is to get another 2 of these moniters and exentually get another 780. But my real question is that is that is it worth gettting a 780ti for the extra $200? http://www.newegg.com/Product/Product.aspx?Item=N82E16814487003
