I own a Palit NVIDIA Geforce 1080 Game Rock.
In previous years, I tended to avoid Palit/Gainward (They are the same company) and bought instead from ASUS/Gigabyte, and the reason I avoided them is:
These GPU's are Chinese and there are horror stories on the internet of people with failed Palit/Gainward GPU's who were asked to ship their failed Gpu's to Hong-Kong -on their own expenses- in order to get a replacement GPU AND pay for return shipment. This is the best case scenario because others who contacted Palit/Gainward on warranty issues were told that Customer Support is given in Mandarin only and it's too bad that they don't speak it.
So, it was after much thought and deliberation that I bought a Palit GTX 1080 Game Rock (dirt freaking cheap too, just 500 euros) from Amazon.de, after I read that Amazon.de offers their own warranty on Palit/Gainward cards. They offer a 30-days no-questions-asked money back guarantee as well as an unoconditional two-year warranty after purchase, wherein you just return the card to them and they send you a new one or your money back, whichever you prefer.
I've owned the card for about 7 months now and I have had no issues with it.
So, I recommend you buy Palit/Gainward if you buy from Amazon and I recommend to NOT buy Palit/Gainward if you don't.
