right now i have two 4850s in cf at 1920x1200. although it is fine or more than fine for most games im experiencing some trouble with frames while playing RvR in WAR. im just wondering what would be the better solution if anyone knows, two 4870s in cf or a 4870x2? system specs are as follows...q9450 stock speeds, dfi lan party ut x48, 4gigs of muskin, pcpc750w, velociraptor300, antec1200.
