Thought I would post this here to show maybe someone debating between the Classified and 780Ti the performance difference. Don't have to much time to run test but I will have another Classified here tomorrow maybe it OC's better for mem and will have another 780Ti so will run some sli test comparing the two and some more single test but here are some quick runs I knew I had stable on both.
780 Classified Stock Sky Bios
780Ti Stock Sky Bios
780 Classified OC using same voltage as the 780Ti 1.21v
