Hi I built myself a PC a while a go, original specs was GTX 1050ti, Ryzen 5 1500x, 8gb DDR4 RAM, Asrock 320m-dgs motherboard, and 450w PSU. Now I upgraded my GPU to 1080 8gb, and got a 750w psu. But the problem is that I thought a GTX 1080 would be overkill for 1080p 75 fps gaming, and moust games dont run so well. Fallout 4 lowers to 45 fps in city area, 2013 Tomb Rider benchmark shows 50 fps avarage, and cant get stable fps on ESO... Also yah, I have a 1080p 75hz freesync monitor, but its temporary. Is it normal, does one of the parts drops my fps?
