I have a amd a8 6500 and a gtx 750 ti. Will getting an upgrade to an i5 6600k increase fps or keep it more stable to it doesnt drop to 20 fps because i normally get 30-40 and i want it to stay atleast constant 40.Ill be getting a new gpu soon too. But will the cpu upgrade boost fps a bit? Im making a whole new build but keepsing the graphics card.
