1- Reference Cards.
These come from Nvidia directly and usualy the first thing to be released to all vendors. Vendors have all ready put there custom coolers and some have played with the clocks too.

4- EVGA GeForce GTX 980 Ti Classified
EVGAs 980 ti Classified is the first 980 ti with an open voltage controller (until kingpin edition that is). The current avaliability of the card is reaching vaporware due to the high demand!
PCB Shots:
VRM: 14+3!

7- Zotac GeForce GTX 980 Ti AMP! Extreme
As far as I know, Zotac was the second with a custom PCB for the 980 ti to be released to the public. With a strong cooling and decent PCB it was a fair shot at the masses. Only gripe it was a 3-slot cooling on launch.
