Upgrade your CPU which is from 2006 to an intel i3 or i5 from any year.
I would recommend the i3-8350k.
i3 is budget, i5 is performance, and i7 is for professional use and is usually not much better at gaming than i5.
Here's a comparison between Intel Core2 E6550 from 2007 (better than your E6300) and an Intel i5-2500k from 2011 (the CPU I have and will soon switch out).

Notice that the i5 has a 190% faster single core computation speed than what the Core2 CPU has.
