As requested by PM, here is a €600 build. Links to the Bulgarian vendor are below the build. G4600 is not as nice as a Ryzen 1400 but the 1400 doesn't fit in the budget and the G4600 should keep up to the 1050 Ti, runs at about the same level as an i3-6100. And its cheaper than the G4560, go figure.

I mean, come on, €2 below budget
Of course GPU pricing is nuts.
