I want to build a new computer to play mildly graphic intense games, (CS:S, TF2). I was considering two http://www.newegg.com/Product/Product.aspx?Item=N82E16814261014 (PALiT nVidia 9600 GSO 768MB in SLi). I was wondering if anyone has had any experience with these cards (or the brand for that matter). Will they be good for running my games? The rest of my PC specs are in my sig.
