The performance is estimated at about 85 percent of a Geforce GTX 690 .
What surprises me is the release date of Late February.
Going by this chart
http://www.guru3d.com/articles_pages/vga_charts_summer_2012,12.html
one 780 Titanium would be @ 1920x1200 85% of 99fps or 84 fps
Making this new card 150% faster than a 680 and 140% faster than a 590
I might have to wait for 790, tough decision
