Hi all I am in a bit of bother lol with choosing between these I currently have a Msi 7950 3gb which I have been happy with but want to be able to play games in 1080p at ultra settings with as many frames as possible I have a 120hz monitor and would like a smoother experience when playing games like bf4 crysis 3 etc which one would be the better upgrade and will last me for a few years thank you
