Once more we've been searching Canard-PC for validations of upcoming hardware and this time we found proof, that NVIDIA already has GTX 780 cards up and running.
Towards the end of last week Fudzilla posted a news that by the end of this month NVIDIA will release their upcoming generation of graphics cards. Those cards will be based on the GK110 as well as on an improved GK104 chip.
In the meantime we have found a first CPU-Z validation which shows proof of NVIDIAs upcoming GTX 780. Unfortunately CPU-Z validations don't contain a lot of information regarding graphics cards. Never the less, the fact that there is a validation means, that there are working samples. In other words, it get more and more likely that NVIDIA is going to launch the new 7-Series cards by the end of this month.
