well your gpu is an hd 7790 .... not the best gpu to play the actuals games ....but at the medium setting no problem
of course in the futur you will need a better gpu ... above all with only 1gb memory???
but for now it will be ok at medium setting like i said , if you save some penny you can afford a gtx 760 for 250$ approx in the futur and with the next futur games , that will be necessary.
