The 4th gen i5 you have bottlenecks no GPU on the market. You can keep it for several years.

Of course if you play CPU intensive games and your processor utilisation is on 100% while gaming you may consider. Keep in mind, that an upgrade would mean that you need a new motherboard and it may well be new RAM modules. So it would cost you over 400$.
