14 DAY TRIAL // NVIDIA hasn't been openly saying much about the GeForce GTX 780 and 770 graphics adapters, since they are unannounced products and it won't comment on unannounced products.
Leaks are still happening all over the place though, and Fudzilla has one that people might appreciate.
Long story short, the two high-end video adapters will make their appearance this month, May 2013.
The GTX 780 will rely on the GK110 GPU and will debut on May 23. It will be 30% faster than GTX 680.
The GTX 770 will arrive on May 30 and will use the GK104-425 core, a stronger iteration of GK104. It will be 20-25% better than GTX 670.
Assuming that the prices carry over from the previous-generation boards, the newcomers may be good deals.
In any case, the adapters will be good enough to tidy people over until Maxwell-based GeForce 800 cards arrive in 2014.
