I have a core i3 currently i3 2120 which runs at 3.3 Ghz with the hd7790 graphics card But my Watch dogs lags at medium settings. However in official requirements of watch dogs my card is the recommended one. So should i buy a core i5 with this graphics card?? will an i5 increase the performance of my card?? or Hd7790 wont be enough with an i5, will it bottleneck i5??
