NVIDIA GTX 780 and 770 Coming May 23rd

At least according to Fudzilla. And they have more info as well. It seems they are slower than the Titan, and are in fact internally known as the Titan LE. The 780 should be 30% faster than the 680 and the 770 should be 20-25% faster than the 670.

The NVIDIA Geforce TITAN does work in a MacPro!

Netkas has posted that yes the incredible $1000 single CPU GeForce Titan does work in the MacPro with the updated NVIDIA drivers in OS X 10.8.4. How is the power draw though? Would it work without external power is the question? It is supposed to draw 250 watts vs the 670's 170 watts, so I am assuming that is way too much.
