Based on the leaks so far it's looking very much like that at stock the 290X trades blows with the Titan, but.. We all know that when overclocked the 780 can surpass the Titan. Considering most 780's are good for 1250mhz+ on the core, and Kepler being more power efficient, I would say Nvidia still have the edge here. These leaks are to be taken with pinch of salt though.
Nvidia is in a world where they have to change markets.
they lost the gaming arena and a console with steam wont save them.
its all slowly happening right now.
