I bought a Dell computer to do work and occasionally to play games. It came with an i7-4970k and 12gb of ram. The stock gpu I had was a gtx 745 4gb. I'm trying to update my gpu so I can run games at a higher frame rate and at 1080p easily. Currently I can only go a bit higher than 720p but my frame rate Is apx less than 25. Does anyone have any recommendations for a good gpu that I can run games 1080p easily at apx 60 fps
