Have an i5 series in my PC as well, the period around 2010 is when things shot up for PC tech as I think Crysis raised the bar on pushing tech so CPUs and GPUs were being produce to run games of that standard as a minimum. The result is that the tech released has now got a ridiculously long shelf life even though new tech is still rapidly being produced resulting in powerful tech becoming cheaper, an i5 and any good GPU will probably see you through even the gen after this one.
