My GPU is always on 0% in the task manager, even while playing games. I have a AMD Radeon HD 8490 in a Dell Optiplex 9020 SFF. Games don't play very well and I'm not sure if it is because it is not being utilised or if I just need to get a better GPU. I want to upgrade to a GTX 1050 Ti Low Profile but I'm not completely sure if it will work.
