why an older and slower intel that costs more? doesnt make any sense.
for software that runs on cores (which his does), the fx 8350 will be enough, ryzen would be way faster,
while costing the same as the quad intel right now.
and for a "future proof/workstation" i wouldnt go with less than 32gb, as its "risky" to add another kit later, as its questionable if you can get not only the same kit again, but one that has the same type of chip.

if you need something now, it should be something like the fx.
in a few month you could get a ryzen based rig.
and again: if we know what area/country, its easier to put stuff together not only thats available but also to get an idea on cost.
i based this on lowest price while still looking at quality components. you can add things like the ssd/water cooler (oc cpu) later,
i included monitor and 32gb ram.
use the old win7 license you already have (laptop), just dl the win 7 x64 or see if friend/family can burn you a copy (needs to be MS edition, not from computer maker like dell/hp etc as those most are restore images, not the OS dvd).
