GTX980 is disappointing in 4K. GTX780Ti is trouncing it in all but one 4K tests. Not surprising maybe, although it has more memory, it's only 256 bit. So I guess price is making sense, anything higher would be overkill.

Damn this is already out now too LOL.

funny the benchmarks don't include new sampling like MFAA - which is 2x the performance over MSAA
and the fact maxwell is meant for serious overclocking according to Jen Sung CEO Nvidia at Game24
Nice Announcement and details
 
Jen Sung said it's the fastest GPU - faster than titan
 
Benchmarks don't include any new tech released with the card in the tests
you use 1/2 the power and get 2x the perfomance over kepler
 
then you add in the extras features the other cards can't do
 
Nvidia announced four new features that promise to make games look more realistic: Dynamic Super Resolution, Multi-Frame-Sampled Anti-aliasing (MFAA), Voxel Global Illumination, and VR Direct.
 
bandwidth is doubled by Compression - so using the same bandwidth they can provide twice the detail and data
 
they re-engineered so it use 1/2 the power to do the same job per core

 The new Maxwell architecture is also dramatically more power efficient than Kepler—the 980 can deliver 30 gigaflops per watt, versus just 15 gigaflops per watt for the 680 and 780. That's allowed Nvidia to bring the card's thermal design point down to 195 watts, and to once again run off two 6-pin connectors.

in fact the Nvidia stock model is 165 Watt GTX980
 

New architechture, still mid range chip (this time blatantly), another $50 and no new node. Laughed so hard at these.
