Yes i know another what graphics card question 
Looking to replace my current 6870 xfire setup with a new card but cant decide which ??
My thoughts are either:
590
6990
7990
Or maybe another xfire or sli set up ?
I want to beable to play games on ultra settings and not have to worry about lag
Read a lot of reviews and opinions but cant make my mind up ?
I currently play WoW and BF3
Thanks
Craig
