i5 4670 vs i5 7500?

[lumencreative]

In work we have 4 Dell Optiplex 3020 PC's that all run i3 CPU's. The were originally purchased for office tasks but are increasingly being used for Photoshop work and are struggling to keep up.

I have looked at the compatibility lists and can upgrade the CPU's to i5 4670's which I can buy for around £50 or so. Alternatively, I can replace the whole PC's for some slightly newer models with i5 7500's for a couple of hundred pounds.

Which would you say is my best option? The Dell's are working well other than the above but part of me worries that if I upgrade the CPU's, the PC's might die in a while due to age anyway.

The CPUs are pretty much on par, so it's down to if you want fresh warranty with the new boxes or not.

Photoshop is generally memory hungry, you might want to investigate memory usage as well. I know my father who is a graphic artist still uses an imac with an i3, the biggest difference for him was upgrading to 16gb ram and an ssd.
