I was lucky enough to get my hands on 2 brand new GTX 1080 custom cards.
The beasts are from Palit and are heavily overclocked out of the box. Boost clock goes up to 2 Ghz and the GDDR5X memory runs at 10500 Mhz. The model number is: GeForce® GTX 1080 GameRock Premium Edition.
To make the upgrade worthwhile I added another 32 GB of RAM and a 1TB SSD:
All went very well and the cards are running like crazy. Not a single crash or other issue so far. The big triple slot coolers keep the cards cool even with limited spacing and SLI cooking.
I have to say: Well done Palit, this cards rock^^
Fancy NVIDIA HB SLI Bridge is already ordered and will be put to hopefully good use soon.
