I currently run the i5-2400 rig with a sapphire nitro 380 and still be able to run most AAA games at decent rates, but this rig is almost 5 years old. My question would be is it worth the upgrade to i5-7600k, the upgrade would also entail changing the PSU (already 5 years old - coolermaster watts) and a Asus B51 motherboard (i think) and of course replacing the DDR3 memory on it.
