hi, i have an old evga gtx 970 that i havent used in a while. mayb about 1-1.5yrs? I decided to build a 2nd pc and used the gtx 970. but at first it wasnt detecting it. i took it out and started using an hd 7950 card for a while. then i tried again after a while. mayb a couple months later. i uninstalled and cleaned the pc off of amd drivers and etc. and it started detecting the gtx 970 as an r9 270x? I decided to just run with it and see how games would run on it even w/o installing drivers. it ran games pretty smoothly. but im jus wondering why it wont detect as a gtx card.
