I'm looking for used GPUs . I'm living in Turkey and almost whole PC components are expensive in my country. When this is in case i should buy used GPU. I've found used GTX 680 2GB. How does it perform nowadays? I know it's an old card but i've heard it performs between GTX 1050 Ti- GTX 1050 and also power hungry card. My PSU can easily handle this card. When is GTX 680's support ends? I've heard kepler GPUs support will end in 2020.
