I just got a used GTX 560 ti off of eBay, and my frame rate in the 3 games I played has just been horrible. Borderlands 2 ran around 20-30 fps when I tested it at 1080p, and 720p gave me like a 5-10 fps increase. Rocket league, high settings @ 1080p ran 60 fps at the menu, but when I got in game it ran around 10 fps, and in the menu after that, 20 fps. Turning down settings didn't do too much. CSGO ran around 30-40 fps @ 1080p low settings. Tried turning down to 720p and it actually got even worse. Anyone know why?
